UBUNTU: SAUCE: omap3: beaglexm: fix DVI initialization

Function beagle_twl_gpio_setup is called after beagle_display_init, what
makes lets reset_gpio with an invalid value at the time it request the
gpio. As a side effect the DVI reset GPIO is not properly set.

Also removing old code that power down DVI in a hardcoded way, as it's
not necessary anymore.

Tested with Beagle-xM and C4.
