[PATCH v8 3/3] arm64: dts: reset: add microchip sparx5 switch reset driver

This provides reset driver support for the Microchip Sparx5 PCB134 and
PCB135 reference boards.

The Sparx5 Switch will no longer use the Ocelot Chip Reset Driver (with the
compatible string "microchip,sparx5-chip-reset"), but use a separate driver
that exposes a reset controller interface and has the compatiple string
"microchip,sparx5-switch-reset".

Eventually the Sparx5 reset support will be removed from the Ocelot chip
reset driver.
