Implement detect() by checking the hot plug detect status.
The implementation is not very good, as it always turns on the HDMI
output to get the detection working. HDMI driver needs improvements so
that we could enable only core parts of it.

check_timings() is supposed to be used to verify if timings are ok or
not. Currently the HDMI driver prints error messages if the timings are
not ok. This is not right, as it is no error to give invalid timings to
check_timings().
Remove the error prints.

OMAPFB handles EDID parsing now, using the common helper functions in
fbdev. We can remove the EDID parsing from HDMI driver.

Implement read_edid() for HDMI by implementing necessary functions to
hdmi.c and to hdmi_omap4_panel.c.

Currently the set_timings code for hdmi is quite strange. The display is
disabled in hdmi_omap4_panel.c before setting timings, and enabled in
hdmi.c after setting the timings. Furthermore, the timings were not
permanent, and disabling and enabling the display would lose them.
This patch makes the set_timings handling a bit better.

As the panel driver will remain generic across OMAP's renaming it to
hdmi_panel.c
