ppc64/ppc64asm,ppc64map: fix BHRBE argument translation

BHRBE stands for "branch history rolling buffer entry". This is not
an SPR. Treat it as an unsigned immediate type argument.

Similarly, DCRN, SR, TMR, PMRN fields are no longer present in ISA 3.1,
they can be removed and nearby code simplified.

Fix ppc64map and update tables.go.
