mb/purism/librem_cnl: move setting of FSP-M UPDs into variant.c

The upcoming Librem 14 variant won't use the same SATA HSIO adjustments
as the Librem Mini, so move these settings into a variant-specific file.

Rename existing gpio.h to variant.h, move to board root directory, and
use for all variant-specific declarations; adjust references as needed.

Add newly-created variant.c to Makefile.

Test: build/boot Librem Mini, verify SATA functionality unchanged.
