When the display turns off, the MSM8974
needs to set ondemand governor's sync_freq

from other targets. To accomplish this, override
the handling for set_interactive. Also refactor
power HAL to remove unnecessary macros.

Process video decode hints and display-off hints
in the power HAL. Also move to using the perflock
API to request system-level parameter changes.
