[U-Boot] [PATCH] build: imx: Fix 'u-boot.imx' build without full OBJTREE reference

[Otavio Salvador]

When calling 'make u-boot.imx' the build were failing as it were
expecting the full path for the file; this regression has been
included by commit 71a988a (imximage.cfg: run files through C
preprocessor).

The direct references for u-boot.imx were replaced by $(obj) as
config.mk handles the proper setting of it making it set to $(OBJTREE)
when required.

The build has been test using './MAKEALL -s mx5 -s mx6' and direct
call to 'make u-boot.imx'.
