[PATCH 3.10 056/104] pinctrl: sunxi: Honor GPIO output initial vaules

[Greg Kroah-Hartman]

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.
