OMAP: DSS2: HDMI: improve hdmi output enable
Enabling HDMI output often causes sync lost errors, and almost always causes timeout errors being printed from dispc_mgr_enable_digit_out(). The sync lost problem seems to go lessen greatly if we first enable the HDMI output, and only then enable the DISPC output. However, as this is only based on observations, the fix may not be perfect as the problem may lie somewhere else. Nevertheless, HDMI works better with this patch. This will also fix the dispc's dispc_mgr_enable_digit_out(), as the code waits for two VSYNCs after enabling the output. If the HDMI output is disabled (as it was previously), there are no VSYNCs and dispc_mgr_enable_digit_out() will print timeout errors.
