[OE-core] [PATCH] kernel-fitimage.bbclass: Allow set/unset load address for FDT

[Nikunj Kela]

Allow the load address for the FDT segment in the fitImage. This
allows U-Boot to dynamically decide where to load the FDT.

UBOOT_FDT_LOADADDRESS - Specifies the load address used by u-boot
		for the FDT
