The Agilex devkit supports a separate eMMC daughter card. The
eMMC daughter card replaces the SDMMC slot that is on the default
daughter card and thus requires a separate board dts file.

Move dma-controller node under simple-bus node to allow bus node specific
property able to be properly defined. This is require to fulfill Agilex5
bus limitation that is limited to 40-addressable-bit.
Update the compatible string for the DMA controller nodes in the Agilex5
device tree from the generic "snps,axi-dma-1.01a" to the platform-specific
"altr,agilex5-axi-dma". Add fallback capability to ensure driver is able
to initialize properly.
This change enables the use of platform-specific features and constraints
in the driver, such as setting a 40-bit DMA addressable mask through
dma-ranges, which is required for Agilex5. It also aligns with the updated
device tree bindings and driver support for this compatible string.

Add the `dma-coherent` property to these device nodes to inform the
kernel and DMA subsystem that the devices support hardware-managed
cache coherence.
Changes:
- Add `dma-coherent` to `cdns,hp-nfc`
- Add `dma-coherent` to both `snps,axi-dma-1.01a` instances
(dmac0, dmac1)
This aligns the Agilex5 device tree with the coherent DMA-capable
devices accordingly.

Introduce the Stratix10 SoC Service Layer (SVC) node for Agilex5 SoCs. This
node includes the compatible string "intel,agilex5-svc" and references a
reserved memory region used for communication with the Secure Device
Manager (SDM).
Agilex5 introduces changes in how reserved memory is mapped and accessed
compared to previous SoC generations. This commit updates the device tree
structure to support Agilex5-specific handling of the SVC interface.

Agilex5 includes an ARM SMMU v3 (System Memory Management Unit) to provide
address translation and memory protection for DMA-capable devices such as
PCIe, USB, and other peripherals.
This commit adds the SMMU node to the Agilex5 device tree with compatible
string "arm,smmu-v3", along with its register space and interrupts.
The SMMU is required to:
- Enable DMA address translation for devices that cannot directly access
the full physical memory space.
- Provide isolation and memory protection by restricting device access
to specific regions of memory, improving system security.
- Support virtualization use cases by enabling safe and isolated device
passthrough to guest VMs.
- Align with ARM platform architecture requirements for IOMMU support.
By describing the SMMU in the device tree, the Linux IOMMU framework
can probe and initialize it during boot. Devices in the system can then
bind to the SMMU via the `iommus` property, enabling memory translation
and protection features as expected.
The following devices are updated to reference the SMMU:
- NAND controller
- DMA controller
- SPI controller
This change is a necessary step toward full enablement high-speed
peripherals on Agilex5.

The "arm,armv8-pmuv3" compatible is intended only for s/w models. Primarily,
it doesn't provide any detail on uarch specific events.
There's still remaining cases for CPUs without any corresponding PMU
definition and for big.LITTLE systems which only have a single PMU node
(there should be one per core type).

The "stmmaceth-ocp" reset line on the SoCFPGA stmmac ethernet driver is
the same as the "ahb" reset on a standard stmmac ethernet.
commit ("843f603762a5 dt-bindings: net: snps,dwmac: Add 'ahb'
reset/reset-name") documented the second reset signal as 'ahb' instead
of 'stmmaceth-ocp'. Change the reset-names of the SoCFPGA DWMAC driver to
'ahb'. In order not to break ABI, we will keep support in thedwmac-socfpga
