[U-Boot] [PATCH] common: board_f: Dont relocate FDT incase of CONFIG_OF_EMBED

[Michal Simek]

From: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com>

Done relocate fdt incase of CONFIG_OF EMBED as the fdt is
already embedded with u-boot image. Also update the fdt_blob
correctly in this case
