MIPS: Add support for vmlinuz.bin appended dtb
Add support for detecting a vmlinuz.bin appended dtb and overriding
the boot arguments to match the UHI interface.
To ensure _edata / __apendend_dtb points to the actual end of the
binary, align the data section to 16 bytes instead of the address
cursor.
Due to ld.script not going through the preprocessor, we can't check
for MIPS_ZBOOT_APPENDED_DTB being enabled, so always reserve space
for it. It should have no consequences for booting without it enabled
except 1 MiB more ram usage during the uncompressing stage.
