[PATCH] OMAP: ZOOM2: Change GPIO to enable LCD NEC NL8048HL11-01B on OMAP34x-II MDP

[Yanick Saugy <yanick.saugy@heig-vd.ch>]

The PIN which controls LCD's reset signal (VGA_nRESET/h_GPIO_96) was not
configured as a GPIO. We had to modify the OMAP MUX, and select this PIN
(CAM_XCLKA) as an output GPIO (OMAP_MUX_MODE4). (kernel 2.6.35)

Be aware of changing this PIN will probably disable the camera, because
it was previously configured as a camera clock.
