arm64/sysreg: Add _EL1 into ID_AA64ISAR1_EL1 definition names 

Normally we include the full register name in the defines for fields within
registers but this has not been followed for ID registers. In preparation
for automatic generation of defines add the _EL1s into the defines for
ID_AA64ISAR1_EL1 to follow the convention. No functional changes.
