bootm: mips: Remove boot_reloc_ramdisk

Remove the function boot_reloc_ramdisk in the file arch/mips/lib/bootm
because it is relocating again the ramdisk. The function do_bootm_states()
already relocates the ramdisk even if it is a legacy uImage or a FIT image.

The relocation in the function do_bootm_states() was introduce in the
commit c2e7e72b ("bootm: relocate ramdisk
if CONFIG_SYS_BOOT_RAMDISK_HIGH set")
