Anurag Singh c2140b83b8 power: vote to turn off io_is_busy for interactive governor 
If the interactive governor is being used, vote to turn off
io_is_busy when video encode starts to reduce power consumption.

Vince Leung 6af746075f powerhal: add opcode to disable sync on thread migration 
Add and use the opcode to disable synchronization
of cores on foreground thread migration.
Synchronization of cores on foreground thread migration
feature is on by default so we will disable
when the display is off and encode/decode hints.

Vince Leung 735a2f98c5 power: add display off and power collapse enable opcodes. 
Display off opcode used to inform PerfLock the display is off.
Power collapse enable opcode allows users to enable power collapse
modes on all cpus.

Anurag Singh daa8f718d8 power: introduce 8974-specific handling 
When the display turns off, the MSM8974
needs to set ondemand governor's sync_freq
and optimal_freq parameters to values different
from other targets. To accomplish this, override
the handling for set_interactive. Also refactor
power HAL to remove unnecessary macros.
