arm64/sysreg: Standardise naming for CTR_EL0 fields
cache.h contains some defines which are used to represent fields and
enumeration values which do not follow the standard naming convention used for
when we automatically generate defines for system registers. Update the
names of the constants to reflect standardised naming and move them to
sysreg.h.
There is also a helper CTR_L1IP() which was open coded and has been
converted to use SYS_FIELD_GET().
