warp7: Fix DFU support

Currently DFU is not working.

Adjust CONFIG_SYS_MALLOC_LEN and dfu_alt_info so that we are
able to flash u-boot.imx into the eMMC via dfu using the
following method:

=> dfu 0 mmc 0

In the host PC:

dfu-util -D u-boot.imx -a boot

This is the same approach done in the mx6sl warp board.
