This patch series adds basic support for Microchip LAN969x SoC.

It introduces the SoC ARCH symbol itself and allows basic peripheral
drivers that are currently marked only for AT91 to be also selected for
LAN969x.

DTS and further driver will be added in follow-up series.

If the drivers on ARCH_LAN969X are largely shared with those on
ARCH_AT91, should they perhaps depend on a common symbol?

That could be either the existing ARCH_AT91 as we do with LAN966,
or perhaps ARCH_MICROCHIP, which is already used for riscv/polarfire.
