The common folder was initialially created for the common parts of the products based on draco-am355x board family. These are the product lines 'pxm2', 'rut' and the base line named 'draco'!
Adding the new capricorn-imx8 board family, common was enhanced without cleanup.
Move all am355x specifics to a new file 'board_am335x'.
