OMAPDSS: n8x0 panel: handle gpio data in panel driver
The n8x0 panel driver leaves gpio configurations to the platform_enable and disable calls in the platform's board file. These should happen in the panel driver itself. A platform data struct called panel_n8x0_data already exists to hold gpio numbers and other platform data. However, the gpio requests are expected to be done in the board file and not the panel driver. Request all the gpios in the panel driver so that the board files which use the the panel don't need to do it. This will help in removing the need for the panel drivers to have platform related callbacks. Signed-off-by: Archit Taneja <archit@ti.com>
