[PATCH v2 13/38] arm64/sysreg: Standardise naming for MVFR0_EL1

[James Morse]

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 MVFR0_EL1 register use lower-case for feature
names where the arm-arm does the same.

No functional change.
