MIPS: mips-cm: Extend CM accessors for 64-bit CPUs

Browse source

Previously, the CM accessors were only accessing CM registers as u32
types instead of using the native CM register with. However, newer CMs
may actually be 64-bit on MIPS64 cores. Fortunately, current 64-bit CMs
(CM3) hold all the useful configuration bits in the lower half of the
64-bit registers (at least most of them) so they can still be accessed
using the current 32-bit accessors.
