[PATCH 01/14] qemu: arm: Use the generated DTB only when CONGIG_OF_BOARD is defined

[Sughosh Ganu]

The Qemu platform emulator generates a device tree blob and places it
at the start of the dram, which is then used by u-boot. Use this dtb
only if CONFIG_OF_BOARD is defined. This allows using a different
device tree, using the CONFIG_OF_SEPARATE option. This dtb is attached
to the u-boot binary as a u-boot-fdt.bin file
