hw/arm/fsl-imx6ul: Wire in the LCDIF device model

Browse Source 
Instantiate LCDIF as a child object of the i.MX6UL SoC in init and
realize it in the SoC realize path before MMIO/IRQ hookup.

Also make FSL_IMX6UL select CONFIG_IMX6UL_LCDIF and map the LCDIF
region with a 16 KiB size to match the SoC memory map.
