3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen-Yu Tsai <wens@xxxxxxxx>
commit fa8cf57c923e86a693a85aff1df579245a27cbb3 upstream.
Some GPIO users, such as fixed-regulator, request GPIO output with
initial value of 1. This was ignored by sunxi driver.
