arm-trusted-firmware-imx: add new package

Browse Source 
Build ATF images for i.MX8MP. Tested on Kontron OSM-S/BL i.MX8MP.

The default IMX_BOOT_UART_BASE for imx8mp platforms is 0x30890000, which
would be UART2. The Kontron board however uses UART3 as serial debug
console. As a result, after loading BL31 the system hangs.

Setting IMX_BOOT_UART_BASE=auto will fix it.
