davinci: omapl138_lcdk: switch to using TI_COMMON_CMD_OPTIONS
Now that we support using TI_COMMON_CMD_OPTIONS,
we dont have to enable a number of commands explicitly
in the defconfig if we enable TI_COMMON_CMD_OPTIONS.
Enable TI_COMMON_CMD_OPTIONS and regenerate the defconfig
using "make savedefconfig".
CMD_GPIO has been kept disabled because there is no GPIO
support (yet) on OMAP-L138 LCDK.
