KVM: arm64: Allow SMCCC_ARCH_WORKAROUND_3 to be discovered and migrated

KVM allows the guest to discover whether the ARCH_WORKAROUND SMCCC are
implemented, and to preserve that state during migration through its
firmware register interface.

Add the necessary boiler plate for SMCCC_ARCH_WORKAROUND_3.
