mb/amd/gardenia/gpio.c: Convert GPIO to new format

New macros were developed that replace previous way of defining GPIO, with
pin and intention very clear while keeping the table mostly identical to
previous method (there's no pull up or pull down when a GPIO is set as an
output). Change current gardenia table to use the new macros.

TEST=Build Gardenia.
