[PATCH 20/20] cuda/pmu: Make find_via_cuda/pmu init functions

[Nick Child]

Make `find_via_cuda` and `find_via_pmu` initialization functions.
Previously, their definitions in `drivers/macintosh/via-cuda.h` include the
`__init` attribute but their alternative definitions in `arch/powerpc/powermac
/sectup./c` and prototypes in `include/linux/cuda.h` and `include/linux/
pmu.h` do not use the `__init` macro. Since, only initialization functions
call `find_via_cuda` and `find_via_pmu` it is safe to label these functions
with `__init`.
