[U-Boot] [PATCH v4 12/18] warp7: Add Kconfig WARP7_ROOT_PART

[Bryan O'Donoghue]

Adding CONFIG_WARP7_ROOT_PART allows a defconfig to specify which partition
is use as the root partition on WaRP7, this is a desirable change in order
to support a different partitioning schemes. The default is the current
partition #2.
