[meta-freescale] [PATCH v5][meta-fsl-arm-extra] imx6sl-warp: Set EXTRA_IMAGEDEPENDS to u-boot

[Daiane Angolini]

Set EXTRA_IMAGEDEPENDS to "u-boot".

When user copies a .sdcard to the eMMC the bootloader is not updated, but it is
still helpful to generate a U-boot binary and be able to inspect U-boot source code.

The .sdcard image generated after this patch does not include the U-boot binary
which is only built to ease an eventual update.

See how-to override eMMC boot partition on the following link:
