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.

MIPS: Lantiq: Add support for device tree file from boot loader

This fetches the device tree file like it is specified in the MIPS UHI
interface if one was found. This is also used when the device tree file
was appended to the kernel image with cat.
This code is copied from arch/mips/bmips/setup.c.

MIPS: Make MIPS_CMDLINE_DTB default
...
Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied
the arguments from dtb to arcs_command_line to prevent the kernel from
overwriting them.
Since there is now an option to keep the dtb arguments, default to the
new option remove the "backup" to arcs_command_line in case of USE_OF is
enabled, except for those platforms that still take the bootloader
arguments or do not use any at all.

'of_ids is not a structure in "include/uapi/*", so no need to initialize
