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.
