hwc: fix and simplify the idle timeout logic
Fixes the following issue : when non-blended layers are composited
via overlays and blended layers are composited via FB, the idle timeout
does not yield invalidation and re-composition of the layers via SGX
resulting in the increased power consumption when the UI is idle.
The change simplifies the idle timeout logic as follows : SGX only
composition is forced after the idle timeout.
