Enable 32-bit or 64-bit DMA in the macb driver based on the macb
hardware compatibility and it is configured with structure macb_config
in the driver.
The Microchip PolarFire SoC Memory Protection Unit(MPU) gives the 64-bit
DMA access with the GEM, the MPU transactions on the AXI bus is 64-bit
not 32-bit So 64-bit DMA is enabled for the Microchip PolarFire SoC GEM.

Change 'clksel' callback function to allow the code to return a
status.
This patch is a preparation for enabling Arm-Trusted-Firmware (ATF)
in Intel SoC FPGA. This patch does not change functionality.
When using Arm-Trusted-Firmware (ATF) in Intel SoC FPGA, the MMC clock
related register is secure register which is required to be written
via SMC/PCSI call. It is possible that U-Boot fail to write the
register if there is unexpected error between U-Boot and ATF.
As a result, there maybe signal integrity on MMC connection due to
clock. So, the code should reports error to user when 'clksel' fail.

ARMv8's generic timer[1] picks up it's graycode from GTC. However,
the frequency of the GTC is supposed to be programmed in CNTFID0[2]
register prior to enabling the GTC in CNTCR[3] register.
In K3 architecture, GTC provides a central time to many parts of the
SoC including graycode to the generic timer in the ARMv8 subsystem.
However, due to the central nature and the need to enable the counter
early in the boot process, the R5 based u-boot enables GTC and
programs it's frequency based on central needs of the system. This
may not be a constant 200MHz based on the system. The bootloader is
supposed to program the FID0 register with the correct frequency it
has sourced for GTC from the central system controller OR from PLLs
as appropriate, and TF-A is supposed[4] to use that as the frequency for
it's local timer.
Currently we are programming just the CNTCR[3] register to enable the
GTC, however we dont let TF-A know the frequency that GTC is actually
running at. A mismatch in programmed frequency and what we program for
generic timer will, as we can imagine, all kind of weird mayhem.
So, program the CNTFID0 register with the clock frequency. Note:
assigned-clock-rates should have set the clock frequency, so the only
operation we need to explicitly do is to retrieve the frequency and
program it in FID0 register.
Since the valid in K3 for GTC clock frequencies are < U32_MAX, we can
just cast the ulong and continue.

The schedule for deprecating the features of the pre-driver-model puts
2019.17 as the deadline for the video subsystem. Furthermore, the latest
patches applied to the am335x-fb.c module have decreased the amount of
code shared with the pre-driver-model implementation. Splitting the two
implementations into two modules improves the readability of the code
and will make it easier to drop the pre-driver-model code.
I have not created a header file with the data structures and the
constants for accessing the LCD controller registers, but I preferred to
keep them inside the two c modules. This is a code replication until the
pre-driver-model version is dropped.

The patch configures the display DPLL using the functions provided by
the driver model API for the clock. The device tree contains everything
needed to get the DPLL clock. The round rate function developed for
calculating the DPLL multiplier and divisor and the platform routines
for accessing the DPLL registers are removed from the LCD driver code
because they are implemented inside the DPLL clock driver.

The previous version of am335x-fb.c contained the functionalities of two
drivers that this patch has split. It was a video type driver that used
the same registration compatible string that now registers a panel type
driver. The proof of this is that two compatible strings were referred
to within the same driver.
There are now two drivers, each with its own compatible string,
functions and API.
Furthermore, the panel driver, in addition to decoding the display
timings, is now also able to manage the backlight.
