arm64/sysreg: Standardise naming for ID_DFR0_EL1

Browse source

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_DFR0_EL1 register have an _EL1 suffix,
and use lower-case for feature names where the arm-arm does the same.

The arm-arm has feature names for some of the ID_DFR0_EL1.PerMon encodings.
Use these feature names in preference to the '8_4' indication of the
architecture version they were introduced in.

No functional change.
