mb/purism/librem_cnl: convert to using overridetrees

Convert the librem_14 and librem_mini from using separate devicetrees
to using a baseboard devicetree and overridetrees. This reduces code
duplication, and facilitates adding any new variants with minimal
additional code.

Test: build/boot Librem 14 and Librem Mini v2 boards
