[PATCH v2 3/3] riscv: dts: microchip: add the Aldec TySoM's devicetree

[Conor Dooley <conor.dooley@microchip.com>]

The TySOM-M-MPFS250 is a compact SoC prototyping board featuring
a Microchip PolarFire SoC MPFS250T-FCG1152. Features include:
- 16 GiB FPGA DDR4
- 16 GiB MSS DDR4 with ECC (Although only 2 GiB is mapped in the
  FPGA design)
- eMMC
- SPI flash memory
- 2x Ethernet 10/100/1000
- USB 2.0
- PCIe x4 Gen2
- HDMI OUT
- 2x FMC connector (HPC and LPC)

Specifically flag this board as rev2, in case later boards have an
FPGA design revision with more of DDR available for use in Linux etc.

Changes in v2:
- removed some extra cells properties
- changed filename compatible to rev2
- dropped pcie from fabric.dtsi, does not appear to be mapped to the MSS
