spl: fdt: Record load/entry fit-images entries in 64bit format
The commit 9f45aeb937
("spl: fit: implement fdt_record_loadable") which
introduced fdt_record_loadable() state there spl_fit.c is not 64bit safe.
Based on my tests on Xilinx ZynqMP zcu102 platform there shouldn't be a
problem to record these addresses in 64bit format.
The patch adds support for systems which need to load images above 4GB.
