The obsolete "samsung,timing" dts property is now split into
"samsung,dw-mshc-ciu-div" (for holding the internal DW MMC divider
value) and "samsung,dw-mshc-sdr-timing" (for actual timing values) in
upstream Linux kernel. Rework the driver to make use of new properties
instead of the old one. All affected dts files were already updated
accordingly.

New Exynos chips should implement clock drivers using CCF framework. In
that case corresponding CCF functions can be used to get/set the clock
rates. Moreover, already existing get_mmc_clk() and set_mmc_clk() calls
are only implemented for CONFIG_CPU_V7A (i.e. ARM32 chips). In case of
ARM64 chips that config option is not defined, so build will crash on
linking stage, with errors like these:
ld: drivers/mmc/exynos_dw_mmc.o:
in function `exynos_dwmci_get_sclk':
undefined reference to `get_mmc_clk'
ld: drivers/mmc/exynos_dw_mmc.o:
in function `exynos_dwmci_set_sclk':
undefined reference to `set_mmc_clk'
Fix that issue by using CCF clocks API on ARM64 platforms for getting
and setting the source clock (sclk = SDCLKIN = CIU) rate. To implement
this, first extract the existing ARM32 clock control code into helper
functions with more generic signatures to abstract getting/setting the
sclk rate. Then add CCF clock support to those functions for ARM64
platforms.

Pinmux configuration on ARM64 platforms must be performed during startup
in pinctrl driver using info from device tree. exynos_pinmux_config()
and pinmux_decode_periph_id() are only available on ARM32 platforms, so
don't call those functions on ARM64 platforms. Instead of the latter
function, use "non-removable" property from device tree to derive the
dev_index value.
This fixes next linking errors on ARM64 platforms:
ld: drivers/mmc/exynos_dw_mmc.o:
in function `exynos_dwmci_get_config':
undefined reference to `pinmux_decode_periph_id'
ld: drivers/mmc/exynos_dw_mmc.o:

In case of CONFIG_DM_MMC, host->priv actually holds (struct udevice *),
and not (struct dwmci_exynos_priv_data *). This makes *priv pointer
invalid and may lead to Synchronous Abort during its dereference later
in exynos_dwmci_board_init(). Fix it by extracting
exynos_dwmmc_get_priv() helper from exynos_dwmci_clksel() and using it
for getting the private data in exynos_dwmci_board_init()

Replace fifoth_val property with its fifo-depth counterpart in all DW
MMC drivers. fifo-depth is a common property used in upstream Linux
kernel. The FIFOTH register value will be calculated using fifo-depth
value in DW MMC core (dw_mmc.c). This change reduces code duplication in
platform drivers, and pulls common FIFOTH register value calculation
into core dw_mmc driver where it belongs.

Some DW MMC blocks (e.g. those on modern Exynos chips) support 64-bit
DMA addressing mode. 64-bit DW MMC variants differ from their 32-bit
counterparts:
- the register layout is a bit different (because there are additional
IDMAC registers present for storing upper part of 64-bit addresses)
- DMA descriptor structure is bigger and different from 32-bit one
Introduce all necessary changes to enable support for 64-bit DMA capable
DW MMC blocks. Next changes were made:
1. Check which DMA address mode is supported in current IP-core
version. HCON register (bit 27) indicates whether it's 32-bit or
64-bit addressing. Add boolean .dma_64bit_address field to struct
dwmci_host and store the result there. dwmci_init_dma() function is
introduced for doing so, which is called on driver's init.
2. Add 64-bit DMA descriptor (struct dwmci_idmac64) and use it in
dwmci_prepare_desc() in case if .dma_64bit_address field is true.
A new dwmci_set_idma_desc64() function was added for populating that
descriptor.
3. Add registers for 64-bit DMA capable blocks. To make the access to
IDMAC registers universal between 32-bit / 64-bit cases, a new
struct dwmci_idmac_regs (and corresponding host->regs field) was
introduced, which abstracts the hardware by being set to
appropriate offset constants on init. All direct calls to IDMAC
registers were correspondingly replaced by accessing host->regs.
4. Allocate and use 64-bit DMA descriptors buffer in case when IDMAC
is 64-bit capable. Extract all the code (except for the IDMAC
descriptors buffer allocation) from dwmci_send_cmd() to
dwmci_send_cmd_common(), so that it's possible to keep IDMAC
buffer (either 32-bit or 64-bit) on stack during send_cmd routine.
The insights for this implementation were taken from Linux kernel DW MMC
driver.

The existing API for these functions is different from the rest of
U-Boot, in that any error code must be obtained from the errno variable
on failure. This variable is part of the C library, so accessing it
outside of the special 'sandbox' shim-functions is not ideal.
Adjust the API to return an error code, to avoid this. Update existing
uses to check for any negative value, rather than just -1.

Back when the TPM subsystem was refactored tpm_tis_wait_init() ended up
being called after tpm_tis_init() which initializes values the former needs.
Since we added more TPM chipsets since then sitting on an i2c bus, this patch
folds in tpm_tis_wait_init into tpm_tis_init and makes sure it's called in the
right order regardless of the bus the TPM sits on.

add the defconfig for that, which has just been waiting for that sync.
There are three more fixes: two for the SPI clock setup, which avoids

with GCC 14 for the sunxi TOC0 part of the mkimage tool.
The gitlab CI passed, and I tested the SPI flash on the OrangePi Zero 3
