Nicolas Pitre d3a875444a ARM: MCPM: move the algorithmic complexity to the core code
All backends are reimplementing a variation of the same CPU reference
count handling. They are also responsible for driving the MCPM special
low-level locking. This is needless duplication, involving algorithmic
requirements that are not necessarily obvious to the uninitiated.
And from past code review experience, those were all initially
implemented badly.

After 3 years, it is time to refactor as much common code to the core
MCPM facility to make the backends as simple as possible.  To avoid a
flag day, the new scheme is introduced in parallel to the existing
backend interface.  When all backends are converted over, the
compatibility interface could be removed.

The new MCPM backend interface implements simpler methods addressing
very platform specific tasks performed under lock protection while
keeping the algorithmic complexity and race avoidance local to the
core code.
