drive_add is only used in softmmu/vl.c, so it can be a static
function there, and drive_def is only a particular use case of
qemu_opts_parse_noisily, so it can be inlined.

Also remove drive_mark_claimed_by_board, as it is only defined
but not implemented (nor used) anywhere.

This also helps simplifying next patch.

To avoid exporting if_name, this can be replaced by a string argument 
directly.  But in any case this is okay for this series:
