OMAPDSS: HDMI: hot plug detect fix
commit ca888a7958b3d808e4efd08ceff88913f4212c69 upstream.
The "OMAPDSS: HDMI: PHY burnout fix" commit switched the HDMI driver
over to using a GPIO for plug detect. Unfortunately the ->detect()
method was not also updated, causing HDMI to no longer work for the
omapdrm driver (because it would actually check if a connection was
detected before attempting to enable display).
