[RFC PATCH 08/38] arm64/sysreg: Standardise naming for ID_PFR0_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 ID_PFR0_EL1 register have an _EL1 suffix,
and use lower case in feature names where the arm-arm does the same.
No functional change.
