omap: rx51: Remove tvout code that plays with gpio 40

Commit 60d24eed "Added video data to support tvout on rx51" added code that
tries to assign gpio 40 as OMAP DSS reset_gpio for tvout. This is wrong
since this gpio has nothing to do with OMAP DSS but it is used to control
one switch that selects is the audio jack connected to tvout or audio
circuitry.

This switch is already supported by the RX51 ASoC driver so there is no need
to control it elsewhere. Switch is contolled with ALSA control
'Jack Function' and tvout can be selected with following example:

	amixer -D hw:0 set 'Jack Function' 'TV-OUT'
