arm64/sysreg: Standardise naming for ID_ISAR0_EL1
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_ISAR0_EL1 register have an _EL1 suffix, and use lower-case for feature names where the arm-arm does the same. To functional change.
