Avoid changing display power state on draw wake lock

When Sidekick is controlling the display, any draw wake lock can cause a
sequence of endDisplayControl/setDisplayPowerState/beginDisplayControl
twice, because of DOZE_SUSPEND -> DOZE -> DOZE_SUSPEND transitions.
We can avoid that by telling power manager that display is controlled by
Sidekick, and draw wake locks shouldn't change the display power state.
