Series arm64/sysreg: Convert aarch32 id regs | expand

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.

Ensure symbols for the MVFR2_EL1 register use lower-case for feature
names where the arm-arm does the same.

No functional change.
