[RFC PATCH 06/38] arm64/sysreg: Standardise naming for ID_ISAR5_EL1

Fri Sep 30 07:01:39 PDT 2022
To convert the 32bit id registers to use the sysreg generation, they
must first have a regular pattern, to match the symbols the script
generates.
Ensure symbols for the ID_ISAR5_EL1 register have an _EL1 suffix.
No functional change.
