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.
