supermicro/x11-lga1151/gpio: 4/5 Convert field macros to PAD_CFG

Converts bit field macros to target PAD_CFG_*() macros, which were
hidden in the comments. To do this, the following command was used:

./intelp2m -n -t 1 -p snr -file ../../src/mainboard/supermicro/
x11-lga1151-series/variants/x11ssm-f/include/variant/gpio.h

./intelp2m -n -t 1 -p snr -file ../../src/mainboard/supermicro/
x11-lga1151-series/variants/x11ssh-tf/include/variant/gpio.h

Tested with BUILD_TIMELESS=1

This is part of the patch set
