colibri-imx6ull: migrate pinctrl and regulators to dtb/dm
Migrate pinctrl and regulators to device tree resp. driver model: Ethernet, NAND and UART. Drop BOARD_EARLY_INIT_F as it is anyway no longer used. Enable CMD_DM, CMD_MTD, CMD_REGULATOR and DM_REGULATOR_FIXED. While at it also update copyright period.
