[PATCH 2/3] pinctrl: sunxi: Fix PIN_CONFIG_BIAS_PULL_{DOWN, UP} argument
From: Chen-Yu Tsai <hidden>

According to pinconf-generic.h, the argument for
PIN_CONFIG_BIAS_PULL_{DOWN,UP} is non-zero if the bias is enabled
with a pull up/down resistor, zero if it is directly connected
to VDD or ground.
Since Allwinner hardware uses a weak pull resistor internally,
the argument should be 1.
