MIPS: Allow platforms to specify the decompressor load address
Platforms which use raw zboot images may need to link the image at
a fixed address if there is no other way to communicate the load
address to the bootloader. Allow the per-platform Kbuild files
to specify an optional zboot image load address (zload-y) and fall
back to calc_vmlinuz_load_addr if unset.
