RISC-V SoC Kconfig Updates for v6.10 A few different bits of SoC-related Kconfig work. The first part of this is shared with the DT updates - the modification of all SOC_CANAAN users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away from the k230 that is able to be used in a "common" kernel. The other thing here is the removal of most of the SOC_VENDOR options, with their ARCH_VENDOR equivalents that've been waiting in the wings for 1 year+ now made visible. Due a lapse on my part when originally adding the ARCH_VENDOR stuff, the Microchip transition isn't complete - the _POLARFIRE was a mistake to keep as there's gonna be non-PolarFire RISC-V stuff from Microchip soonTM.
