arm64/sysreg: Align field names in ID_AA64DFR0_EL1 with architecture
The naming scheme the architecture uses for the fields in ID_AA64DFR0_EL1 does not align well with kernel conventions, using as it does a lot of MixedCase in various arrangements. In preparation for automatically generating the defines for this register rename the defines used to match what is in the architecture.
