arm64/sysreg: Standardise naming for MVFR1_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 MVFR1_EL1 register use lower-case for feature names where the arm-arm does the same. No functional change.
