arm64: dts: st: support Engicam MicroGEA-STM32MP257 SoM
Support Engicam MicroGEA-STM32MP257 SoM with:
- 8 GB eMMC Flash
- 2 GB LPDDR4 DRAM
The SoM also provides an Ethernet MAC, but Ethernet support is not
enabled at this stage due to a known silicon limitation documented in
[1].
This corresponds to section 2.21.2 ("ETH1 RMII mode could have CRC
errors"), where CRC errors may occur in ETH1 RMII direct mode when
directly connected to I/Os.
The workaround requires use of the Ethernet switch (ETHSW), which
introduces additional DT bindings and topology complexity. This is
intended to be addressed in a separate patch series.
