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.
