mb/purism/librem_skl: select DRIVERS_GENERIC_CBFS_SERIAL
This driver was previously added for another out-of-tree Librem device, but forgot to switch over the librem_skl boards to use it. Remove duplicate functionality from mainboard.c and delete the empty file. Test: build/boot Librem 13v2 and verify serial number read from CBFS via dmidecode.
