This series does a bunch more conversions of system registers to be
generated, all trivial ones that don't require anything other than the
conversions themselves.

v2:
 - Drop CCSIDR_EL1, CTR_EL0 and DCZID as they had macros referring to
   fields I hadn't found that make them non-trivial.
 - Various minor and typographical updates.

Mark Brown (6):
  arm64/sysreg: Generate definitions for CLIDR_EL1
  arm64/sysreg: Generate definitions for CONTEXTIDR_ELx
  arm64/sysreg: Generate definitions for CPACR_ELx
  arm64/sysreg: Generate definitions for CSSELR_EL1
  arm64/sysreg: Generate definitions for DACR32_EL2
  arm64/sysreg: Generate definitions for FAR_ELx

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.

I do think that in future we may want to define enumerated values for the
FPEN/ZEN/SMEN fields, but with that aside, all the values appear to be correct,
so for this as-as:

Convert FAR_ELx to automatic register generation as per DDI0487H.a. In the
architecture these registers have a single field "named" as "Faulting
Virtual Address for synchronous exceptions taken to ELx" occupying the
entire register, in order to fit in with the requirement to describe the
contents of the register I have created a single field named ADDR.

No functional change.
