arm64/sme: Add ID_AA64SMFR0_EL1 to __read_sysreg_by_encoding()

mainline inclusion
from mainline-v5.19-rc1
commit 8a58bcd0
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8E73O
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=8a58bcd00e2e8d46afce468adc09fcd7968f514c



-------------------------------------------------

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.
