This fixes the battery voltage monitoring gpio-hog settings.

When the gpio is low, it turns off the battery voltage to the ADC chip.
However, this needs to be on all of the time so that we can monitor
battery voltage.

Please disregard this patch. Apparently, pinmuxing on platform devices 
is broken in the linux-davinci master branch, which led me astray.
