[POWERPC] fix cell pmu initialisation

[Stephen Rothwell]

Make sure that the pmu is not initialised unless we are running on a cell.
Also make the init routine static.

After this patch, a combined kernel (including all the 64 bit platforms)
will boot on my Series P 285 (apart from a ata panic which may be
unrelated).

This should be safe for 2.6.20 (I think).
