Enabling HDMI output often causes sync lost errors. The problem seems to go away if we first enable the HDMI output, and only then enable the DISPC output. 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.
