efi: Generalize handle_ramdisks() and rename to handle_cmdline_files().
The handle_cmdline_files now takes the option to handle as a string, and returns the loaded data through parameters, rather than taking an x86 specific setup_header structure. For ARM, this will be used to load a device tree blob in addition to initrd images.
