Add i.MX6ULL EVK board support: Add device tree file, which is copied from NXP Linux. Enabled DM_MMC, DM_GPIO, DM_I2C, DM_SPI, PINCTRL, DM_REGULATOR. The uart iomux settings are still keeped in board file.

The pinctrl driver will configure the pinmux, no need to add iomux settings in board file. In this patchset, I enabled PINCTRL, DM_MMC, DM_GPIO and etc.
Thanks, Peng.
thanks!
