Fix HDMI unblank behavior
Two issues: (1) We were announcing the hotplug event before we were ready to handle blank/unblank events, so we were losing the initial unblank that power manager sends us when HDMI is first plugged in. This left the display blank until you toggled the device power off/on. (2) We were retaining fbTargetHandle for HDMI after the display was disconnected. The value didn't get updated when HDMI was reconnected because the display was blank, so we didn't go through that code path. So, when HDMI was re-connected, we passed stale data into the HWC.
