UPSTREAM: arm64/sme: Add ID_AA64SMFR0_EL1 to __read_sysreg_by_encoding()

We need to explicitly enumerate all the ID registers which we rely on
for CPU capabilities in __read_sysreg_by_encoding(), ID_AA64SMFR0_EL1 was
missed from this list so we trip a BUG() in paths which rely on that
function such as CPU hotplug. Add the register.
