arm64/sysreg: Update SMIDR_EL1 to DDI0601 2025-06

Update the definition of SMIDR_EL1 in the sysreg definition to reflect the
information in DD0601 2025-06. This includes somewhat more generic ways of
describing the sharing of SMCUs, more information on supported priorities
and provides additional resolution for describing affinity groups.
