That version may be similar to what is in the freescale BSP which puts
the clock functions inside flexcan.c

The powerpc arch already provides a means for individual boards to provide
the clock functions.  I am not posting this patch here for acceptance
for powerpc and I am sure I will get feedback there when I post to
their mailing list.  I am posting it here only to show that the flexcan
developers earlier assertion that this can and should be done in the arch
tree is correct and will work for the p1010 assuming we can get changes
into the arch/powerpc directory to implement these clk_* functions.

Thanks,
Robin
