kernel: Backport pending appended DTB handling patches
Backport patches from upstream Linux kernel which are making the kernel stores the appended dtb not in the same resisters as defined in the UHI specification, use a separate variable on MIPS.

+
+Instead of rewriting the arguments, just move the appended dtb to where
+the decompressed kernel expects it. This eliminates the need for special
+casing vmlinuz.bin appended dtb files.

+Subject: [PATCH] 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.
