[PATCH v4 13/28] arm64/sysreg: Standardise naming for ID_AA64PFR0_EL1 constants

[Mark Brown]

We generally refer to the baseline feature implemented as _IMP so in
preparation for automatic generation of register defines update those for
ID_AA64PFR0_EL1 to reflect this.

In the case of ASIMD we don't actually use the define so just remove it.

No functional changes.
