Convert to use DM_PMIC/DM_REGULATOR/DM_I2C for mx6ul evk.
To mx6ul_14x14_evk, there is no pmic on board, so only enable DM_I2C.
Since we have PINCTRL driver and DM_I2C enabled, we could discard
the pinmux setting in board file, but we can not do this, because
still some dependency in arch/arm/imx-common/i2c-mxv7.c. Later
we may need to find out a way to refine this.
To avoid SPL build warning, disable mxc_i2c driver for SPL part.
