mips: add dtb loading support
Kexec for MIPS currently does not support loading devicetrees, unless
they are embedded in the kernel elf file.
Add an option to either pass a new dtb file or - if not specified - to
be generated from existing device tree on the device. As new generic
platforms require a dtb to be passed separately this is required for
such platforms and will be ignored by the kernel otherwise.
Generic kexec infrastructure for dtb support is used.
