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
in da850_lcdcntl_pins structure.

Please ignore this patch. I'll submit the correct patch as
PATCH v3.
