hwc: Delay HDMI/WFD connection request by one frame
This change introduces hdmi pending state, where we allow
frames to fall back to FB, closing all MDP pipes.
Pipes could be used by primary (mixer 0) in which case moving
them to external (mixer 1) involves unsetting them and setting
them in the same round which is not recommended by the driver.
It will fall back to GPU till HDMI is configured on a connect
event.
