arm64/sysreg: Generate definitions for CPACR_ELx

Browse Source 
Convert the CPACR system register definitions to be automatically generated
using the definitions in DDI0487H.a. The kernel does have some additional
definitions for subfields of SMEN, FPEN and ZEN which are not identified as
distinct subfields in the architecture so the definitions are not updated
as part of this patch.

No functional change.
