Let's encapsulate more the PM code inside the PM file by moving the
'exynos_set_wakeupmask' function inside the pm.c and the call in the cpu_pm
notifier.

I'm not sure about this change.
Wake-up mask depends heavily on lower power state being entered, so CPU
idle driver should be able to specify what mask to set. Of course
currently the only state that requires this mask to be set is AFTR, but
there are more states, such as LPA, which may need different value.
Best regards,
Tomasz
