According to the documentation [1], RX Level/Edge Configuration (trig)
and GPIO Tx/Rx Buffer Disable (bufdis) [2] settings are not applicable
in native mode and BIOS does not need to configure them. Therefore,
there is no need to configure this in gpio.h using PAD_CFG_NF_BUF_TRIG
macros. Use PAD_CFG_NF instead and set this fields to 0.

This format of PCH GPIOs configuration, unlike the raw DW0 and DW1
registers values from the inteltool dump, is more understandable and
makes the code much cleaner. The gpio.h file with PAD_CFG macros was
automatically generated using the util/intelp2m [1] utility:
./intelp2m -p lbg -file cedarisland/vendorbios/inteltool_gpio.log
According to the documentation [2], the Host Software Pad Ownership
register only affects the pads that are configured as input. The
intelp2m utility takes this into account when converting macros and
ignores bits from this register for the corresponding pads.

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 vendors firmware. The gpio.h file with pad
configuration was generated automatically using the util/intelp2m [3]:
./intelp2m -raw -p lbg -file cedarisland/vendorbios/inteltool_gpio.log
