initrd: remove deprecated code path (linuxrc)
Remove linuxrc initrd code path, which was deprecated in 2020.
Initramfs and (non-initial) RAM disks (i. e. brd) still work.
Both built-in and bootloader-supplied initramfs still work.
Non-linuxrc initrd code path (i. e. using /dev/ram as final root
filesystem) still works, but I put deprecation message into it.
Also I deprecate command line parameters "noinitrd" and "ramdisk_start=".
