Some 32-bit SPRs are incorrectly implemented as 64-bits on 64-bit
targets.
This changes VRSAVE, DSISR, HDSISR, DAWRX0, PIDR, LPIDR, DEXCR,
HDEXCR, CTRL, TSCR, MMCRH, and PMC[1-6] from to be 32-bit registers.
This only goes by the 32/64 classification in the architecture, it
does not try to implement finer details of SPR implementation (e.g.,
not all bits implemented as simple read/write storage).
