[v2,01/38] arm64/sysreg: Standardise naming for ID_MMFR0_EL1

Commit Message

James Morse Nov. 30, 2022, 5:16 p.m. UTC

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. The scripts would like to follow exactly what is in the
arm-arm, which uses lower case for some of these feature names.

Ensure symbols for the ID_MMFR0_EL1 register have an _EL1 suffix,
and use lower case in feature names where the arm-arm does the same.

No functional change.
