RISC-V: KVM: Add SBI extension validate callback

Browse source

When user disable FWFT extension after setting any value of the
FWFT feature, the state of vCPU will be broken since the value
of disable FWFT feature is still functional.

Add the generic SBI extension validate callback so the FWFT
extension can fix its parameters before the first run.
