Heh these CK_XXXX defines are now running out of the u16 cpu_mask.

They really should be replaced with SoC specific lists of clocks
rather than bloating the cpu_mask and repeating it for every clock
that's compiled in for 800+ times.

Below (untested) is what could be done in the short term.

I wonder if we could #define CK_OMAP_DUMMY 0 that's always set
for non-shared clocks if they only get set in some *_data.c
file in a unique way?

Paul got any better ideas?

Regards,

Tony
