[U-Boot] [PATCH 3/3] imx: mx6ul_evk: convert to use Driver model for power and i2c

[Peng Fan]

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 i2c-mxc driver for SPL part.
