[v3,1/5] imx: mkimage_fit_atf: Fix FIT image if BL31.bin missing

From: Heiko Stuebner <heiko.stuebner at theobroma-systems.com>

Right now if its bl31.bin is missing, the imx make_fit_atf.sh does
return "sucessful" without generating an .its source file, which
makes autobuilders unhappy.

So this change is similar to Tom Rini's
commit 4c78028737c3 ("mksunxi_fit_atf.sh: Allow for this to complete when bl31.bin is missing")
in that it changes the behaviour to a warning and still lets the script
generate a usable u-boot.its and thus also lets the u-boot.itb get build
successfully
