[PATCH V4] ARM: imx: Include u-boot.img in u-boot-with-spl.imx if OF_SEPARATE=y

[Marek Vasut]

The u-boot-with-spl.imx is a concatenation of SPL and u-boot.uim.
The u-boot.uim is u-boot.bin wrapped in uImage. In case OF_SEPARATE
is enabled, the u-boot.bin does not contain control DT for U-Boot,
and so u-boot.uim does not contain the DT, and so u-boot-with-spl.imx
does not contain the DT, and a system where u-boot-with-spl.imx is
written to offset 1024B to the start of storage no longer boots, as
it is missing DT.

In case OF_SEPARATE is enabled, u-boot.img contains both u-boot.bin
and the necessary DTs. Therefore, use u-boot.img instead of u-boot.uim
to generate u-boot-with-spl.imx when OF_SEPARATE is enabled.

V2: Swap the u-boot.uim <-> u-boot.img in the conditional so this would
    match the patch which Fabio originally tested
V3: - Correct the u-boot.img/u-boot.uim dependency in top-level Makefile
    - Drop TB from Fabio, this needs to be retested
V4: Forward the u-boot.uim generation to mach-imx Makefile too
