Anup Patel 071ef070ca KVM: riscv: selftests: Selectively filter-out AIA registers 
Currently the AIA ONE_REG registers are reported by get-reg-list
as new registers for various vcpu_reg_list configs whenever Ssaia
is available on the host because Ssaia extension can only be
disabled by Smstateen extension which is not always available.

To tackle this, we should filter-out AIA ONE_REG registers only
when Ssaia can't be disabled for a VCPU.
