This fixes most PM operations: cpufreq, cpuidle and suspend. Resume does not
work on beaglebone, but 3 out of 4 ain't bad :)
The M3 firmware needed for suspend/resume is used as a binary, building it
from source and including it from sysroots is planned for future commits.
Beaglebone patches have been forward ported and runtime tested.
