[POWERPC] Fix drivers/macintosh/mediabay.c when !CONFIG_ADB_PMU
When building drivers/macintosh/mediabay.c if CONFIG_ADB_PMU isn't
defined we get:
drivers/built-in.o: In function `media_bay_step':
mediabay.c:(.text+0x92b84): undefined reference to `pmu_suspend'
mediabay.c:(.text+0x92c08): undefined reference to `pmu_resume'
Create empty place holders in that scenario.
