Subject: [PATCH v3 1/7] arm64/sysreg: Convert CCSIDR_EL1 to automatic generation

Convert CCSIDR_EL1 to automatic generation as per DDI0487I.a. The field
definition is for case when FEAT_CCIDX is not implemented. Fields WT,
WB, RA and WA are defined as per A.j since they are now reserved and
may have UNKNOWN values in I.a, which the file format cannot represent.
