bootloader: add specific boot options for Raspberry Pi I/O scheduler (deadline)
elevator=deadline is supposed to give better performance on flash
storage, and used by default on most Raspberry Pi distributions.
Ideally, this should not be set here for specific boards, but
automatically for all architectures depending on the storage type.
Archlinux appears to use a /etc/tmpfiles.d/set_IO_scheduler.conf file for this.
