common/image.c: align usage of fdt_high with initrd_high
The commit message of a28afca (Add uboot "fdt_high" enviroment variable)
states that fdt_high behaves similarly to the existing initrd_high.
But fdt_high actually has an outstanding difference from initrd_high.
The former specifies the start address, while the later specifies the
end address.
As fdt_high and initrd_high will likely be used together, it'd be nice
to have them behave same. The patch changes the behavior of fdt_high
to have it aligned with initrd_high.
The document of fdt_high in README is updated with an example to
demonstrate the usage of this environment variable.
