There's only one implementation of mips_cpc_phys_base(), and it's only used
within the same file, so it doesn't need to be weak, and it doesn't need an
extern declaration.
Remove the extern mips_cpc_phys_base() declaration and make it static.

This patch provides functions to lock & unlock access to the
"core-other" register region of the CPC. Without performing appropriate
locking it is possible for code using this region to be preempted or to
race with code on another VPE within the same core, with one changing
the core which the "core-other" region is acting upon at an inopportune
time for the other.

This patch introduces addr_ functions in addition to the existing read_
& write_ functions. The new functions simply return the address of the
appropriate CPC register rather than performing a memory access. This
will be used in a subsequent patch.
