MIPS: store the appended dtb address in a variable
Instead of rewriting the arguments to match the UHI spec, store the
address of a appended or UHI supplied dtb in fw_supplied_dtb.
That way the original bootloader arugments are kept intact while still
making the use of an appended dtb invisible for mach code.
Mach code can still find out if it is an appended dtb by comparing
fw_arg1 with fw_supplied_dtb.
