[ Upstream commit e482eab4d1eb31031eff2b6afb71776483101979 ]
The riscv_cpuinfo struct that contains mvendorid and marchid is not
populated until all harts are booted which happens after the DT parsing.
Use the mvendorid/marchid from the boot hart to determine if the DT
contains an invalid V.
Fixes: d82f32202e0d ("RISC-V: Ignore V from the riscv,isa DT property on older T-Head CPUs")
