src/mb/prodrive/atlas: Add GPIOs for configuration

CLKREQ Pins are intentionally not configured, because there seems to be
a current Issue with FSP, that causes pci devices to not work if CLKREQ
Pins are configured by coreboot. The msi/ms7d25 mainboard seems to have
a similar issue and the cause is also documented in it's gpio.c file.
