[U-Boot] [PATCH 2/3] warp7: Handle mmcroot for mainline and NXP

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at nxp.com>

The rootfs appears at mmcblk2 in the NXP kernel and at mmcblk1 in mainline
kernel.

Load the correct mmcblk device depending on the selection of the
CONFIG_ARMV7_BOOT_SEC_DEFAULT variable.

CONFIG_ARMV7_BOOT_SEC_DEFAULT is selected in warp7_secure_defconfig, which
is used to boot a NXP kernel.
