The ACOK pin on the bq24735 is active-high, of course meaning that when AC is OK the pin is high. However, all Tegra dts files have incorrectly specified active-high even though the signal is inverted on the Tegra boards. This has worked since the Linux driver has also inverted the meaning of the GPIO. Fix this situation by simply specifying in the bindings what everybody else agrees on; that the ti,ac-detect-gpios is active on AC adapter absence.

This patch is the result of this discussion: http://marc.info/?t=148152531800002 I don't like how it changes the one thing that is seems correct, but what to do?
