[meta-freescale] [PATCH v2][meta-fsl-arm-extra] imx6sl-warp: Change IMAGE_BOOTLOADER

[Daiane Angolini]

Set the default value for IMAGE_BOOTLOADER explicitly even though when user
copies a .sdcard to the eMMC the bootloader will not be updated.

WaRP uses eMMC boot partition by default and the u-boot inside .sdcard image
does not override it. However, building u-boot binary anyway in order to provide
a binary to be used if an update is needed see how-to override eMMC boot
partition on the following link
 http://git.denx.de/?p=u-boot.git;a=blob;f=board/warp/README

It is only changed back to default value to ease u-boot manual update for the
user.
