This patch series is trying to add EMAC0 ethernet MAC support
to the A523 variant SoCs, including A523, A527/T527 chips.
This MAC0 is compatible to previous A64 SoC, so introduce a new DT
compatible but make it as a fallback to A64's compatible.
In this version, the PHYRSTB pin which routed to external phy
has not been populated in DT. It's kind of optional for now,
but we probably should handle it well later.
I've tested only on Radxa A5E board.
