Daniel Henrique Barboza 432a8b35cc RISC-V: KVM: do not EOPNOTSUPP in set KVM_REG_RISCV_TIMER_REG 
The KVM_REG_RISCV_TIMER_REG can be read via get_one_reg(). But trying to
write anything in this reg via set_one_reg() results in an EOPNOTSUPP.

Change the API to behave like cbom_block_size: instead of always
erroring out with EOPNOTSUPP, allow userspace to write the same value
(riscv_timebase) back, throwing an EINVAL if a different value is
attempted.
