boot/uboot: copy IMX firmware files to uboot package dir

Browse Source 
The mainline U-Boot can create an i.MX specific firmware image (e.g. flash.bin).
For this the i.MX firmware files (DDR, HDMI) must be in the toplevel directory.

Some i.MX8 platforms (such as i.MX8 M, i.MX 8M Mini, i.MX 8M Nano)
encapsulate NXP specific firmware (DDR, HDMI) inside U-Boot.
This option makes sure that the i.MX firmwares are copied into
the U-Boot source directory.
