mb/google/sarien: Update GPIO GPP_C23 setting
GPIO pin GPP_C23 is used as level trigger but not edge trigger, also it
is not inverted, correct it here. According to board schematic, GPP_C23
connected with 3.3v pull up, so the pin is low active.
BUG=b:128554235
TEST=Boot up arcada platform with stylus keep on touching the screen,
the touch screen is still functional once in OS stage. Without change,
touch screen is not functional at same scenario.
