it8380dev: add pin 3.3v/1.8v selection
add GPIO_SEL_1P8V flag for 1.8v/3.3v selection.
Signed-off-by: Dino Li <dino.li@ite.com.tw>
BRANCH=none
BUG=none
TEST=1. To configure 1.8V/3.3V pin to 1.8V,
set GPIO_SEL_1P8V flag in gpio.inc.
2. The corresponding bit will be set as default value if the pin
is not listed in gpio.inc.
