Subject: [PATCH v3 1/3] init: remove deprecated "load_ramdisk" and "prompt_ramdisk" command line parameters

...which do nothing. They were deprecated (in documentation) in
6b99e6e6aa62 ("Documentation/admin-guide: blockdev/ramdisk: remove use of
"rdev"") in 2020 and in kernel messages in c8376994c86c ("initrd: remove
support for multiple floppies") in 2020.
