davinci: Correct the GPIO number for LCD panel power
On the latest DA850/OMAP-L138 EVM (Beta) the GPIO pin number of LCD panel power has changed. This patch takes care of this change. Software will support only Beta versions of DA850/OMAP-L138 EVM. In the process, add the missing entry for data pin 0 and remove the GPIO specific pins from da850_lcdcntl_pins structure. EVM specific muxing for LCD is being done in the board file now.
