arm64: Allow the definition of UNKNOWN system register fields
The CCSIDR_EL1 register contains an UNKNOWN field (which replaces
fields that were actually defined in previous revisions of the
architecture).
Define an 'Unkn' field type modeled after the Res0/Res1 types
to allow such description. This allows the generation of
#define CCSIDR_EL1_UNKN (UL(0) | GENMASK_ULL(31, 28))
which may have its use one day. Hopefully the architecture doesn't
add too many of those in the future.
