arm64: dts: microchip: sparx5: do not use PSCI on reference boards PSCI is not implemented on SparX-5 at all, there is no ATF and U-boot that is shipped does not implement it as well. I have tried flashing the latest BSP 2022.12 U-boot which did not work. After contacting Microchip, they confirmed that there is no ATF for the SoC nor PSCI implementation which is unfortunate in 2023. So, disable PSCI as otherwise kernel crashes as soon as it tries probing PSCI with, and the crash is only visible if earlycon is used. Since PSCI is not implemented, switch core bringup to use spin-tables which are implemented in the vendor U-boot and actually work. Tested on PCB134 with eMMC (VSC5640EV).

arm64: dts: sparx5: Add basic cpu support This adds the basic DT structure for the Microchip Sparx5 SoC, and the reference boards, pcb125, pcb134 and pcb135. The two latter have a NAND vs a eMMC centric variant (as a mount option).
