Paul Burton b657a62866 MIPS: Allow read64 GCR accessors to work on MIPS32 kernels
If we run a MIPS32 kernel on a system using CM3 we may still need to
access 64 bit GCRs, as will be done in later patches. Allow this by
having the read64_gcr_* accessor functions perform 2 x 32 bit reads on
those systems.
