msm: 8064: add board file structures for mpdecision and msm governor.
Add device structures in the board file for mpdecision and the msm
governor. This essentially probes mpdecision driver and the msm
governor driver. When enabled mpdecision communicates the run queue
average with TZ and obtains back a mask of which cpus should be
online. The msm governor communicates the frequencies of the cpus
with TZ and obtains newer frequency for that cpu.
Both combined they govern which cpus stay online and how fast they
run.
