Fix the value of ID_PFR1_EL1.Security NSACR_RFR to be 0b0010, as per
DDI0601/2025-06, which wasn't correctly set when introduced in commit
1224308075f1 ("arm64/sysreg: Convert ID_PFR1_EL1 to automatic generation").
While at it, remove redundant definitions of CPACR_EL12 and
RCWSMASK_EL1 and fix some typos.

Note that NSACR_RFR isn't used in the kernel as far as I could tell, so
I didn't add a 'Fixes' tag.
