arm64/sysreg: Standardise naming for ID_AA64MMFR1_EL1 fields
In preparation for converting the ID_AA64MMFR1_EL1 system register
defines to automatic generation, rename them to follow the conventions
used by other automatically generated registers:
* Add _EL1 in the register name.
* Rename fields to match the names in the ARM ARM:
* LOR -> LO
* HPD -> HPDS
* VHE -> VH
* HADBS -> HAFDBS
* SPECSEI -> SpecSEI
* VMIDBITS -> VMIDBits
There should be no functional change as a result of this patch.
