[Buildroot] [PATCH 2/2] configs/freescale_imx7dsabresd: Apply upstream U-Boot fix

[Fabio Estevam <festevam@gmail.com>]

NXP U-Boot tree has the following build issue:

  MKIMAGE u-boot-dtb.imx
Error: No BOOT_FROM tag in board/freescale/mx7dsabresd/imximage.cfg.cfgtmp
arch/arm/imx-common/Makefile:91: recipe for target 'u-boot-dtb.imx' failed
make[2]: *** [u-boot-dtb.imx] Error 1
Makefile:877: recipe for target 'u-boot-dtb.imx' failed

This issue has been fixed by commit  f916757300c1  ("imx: Create
distinct pre-processed mkimage config files"), so backport this
commit to the NXP U-Boot tree in order to fix the build error.

+Subject: [PATCH] imx: Create distinct pre-processed mkimage config files
+
+Each imx image is created by a separate sub-make and during this process
+the mkimage config file is run though cpp.
+
+The cpp output is to the same file no matter what imx image is being
+created.
+
+This means if two imx images are generated in parallel they will attempt
+to independently produce the same pre-processed mkimage config file at
+the same time.
+
+Avoid the problem by making the pre-processed config file name unique
+based on the imx image it will be used in.  This way each image will
+create a unique config file and they won't clobber each other when run
+in parallel.
+
+This should fixed the build bug referenced in b5b0e4e3 ("imximage:
+Remove failure when no IVT offset is found").
