mb/tiogapass: use common driver to configure GPIO
According to changes in the soc/xeon_sp code [1,2], server motherboards
with Lewisburg PCH can use the soc/intel/common/gpio driver to configure
GPIO controller. This patch adds pads configuration map, which has the
format required by the GPIO driver. The data for this was taken from the
inteltool register dump with AMI firmware. The gpio.h file with pad
configuration was generated automatically using the util/intelp2m [3]:
./intelp2m -raw -p lbg -file tiogapass/vendorbios/inteltool_gpio.log
