Enable touch boost during camera.

Previously, the video encode hint would hotplug the big cores off while
the camera was running in order to improve thermals and power
consumption. Instead, have the camera run the big cores at 384MHz so we
can still apply POWER_HINT_INTERACTION.

This also restricts mm-qcamera-daemon to the small cluster in order to
prevent it from being boosted by touch boost.
