mb/purism/librem_whl: rename to librem_cnl

Since Whiskeylake SoC code is actually a subset of soc/intel/cannonlake,
rename the baseboard so that boards using other 'cannonlake family' SoCs
(e.g., Cometlake) can be added with minimal confusion.

Rename the mainboard dir and baseboard name, and adjust any references
to them.
