mips: add option to load initrd from a specified file

Use kexec's existing infrastrucutre for supporting initrd loading.
The initrd image is loaded into a buffer after the dtb and its details
passed through the device tree, so it's supported on newer platforms
that make use of the device tree passed from kexec.
