MIPS: smp-cps: Don't rely on CP0_CMGCRBASE

CP0_CMGCRBASE is not always available on CPS enabled system
such as early proAptiv.

For early SMP bring up where we can't safely access memeory,
we patch the entry of CPS NMI vector to inject CMGCR address
directly into register during early core bringup.

For VPE bringup as the core is already coherenct at that point
we just read the variable to obtain the address.
