All calls to mips_cpc_lock_other should be wrapped in
mips_cm_lock_other. This only matters if the system has CM3 and is using
cpu idle, since otherwise a) the CPC lock is sufficent for CM < 3 and b)
any systems with CM > 3 have not been able to use cpu idle until now.

MIPS CM3 changed the management of coherence. Instead of a coherence
control register with a bitmask of coherent domains, CM3 simply has a
coherence enable register with a single bit to enable coherence of the
local core. Support this by clearing and setting this single bit to
disable / enable coherence.

This patch adds support for CPUs implementing the MIPSr6 ISA to the CPS
power management code. Three changes are necessary:

1. In MIPSr6, coupled coherence is necessary when CPUS implement multiple
   Virtual Processors (VPs).

2. MIPSr6 virtual processors are more like real cores and cannot yield
   to other VPs on the same core, so drop the MT ASE yield instruction.

3. To halt a MIPSr6 VP, the CPC VP_STOP register is used rather than the
   MT ASE TCHalt CP0 register.

complete before any loads/stores subsequent to the sync instruction.

In places where we require loads / stores be globally completed, use the
