When the blended background pipe has dropped alpha and it is going to
be blended with foreground pipe on the next stage,
MDP4_BLEND_BG_ALPHA_FG_CONST is taken. Foreground alpha constant is
0xFF, so we need to use this alpha value to show background, instead
of its inverted value.

Currently, HPD(Hot Plug Detection, a module used for detecting
HDMI cable connection) soft debouncing logic implements around
1 sec mechanism to stabilize HPD event detection. In case of
fast HPD connect/disconnect, it is missing a real HPD event.
This change implements a new debouncing logic in driver which
will make sure the first real HPD event is correctly processed
and at the end of debouncing processing, if there is a change
in HPD state, the changed state is also processed. This way we
always process the change of HPD states.
