[PATCH v3 13/25] include/sysemu/blockdev.h: move drive_add and inline drive_def

[Emanuele Giuseppe Esposito <eesposit@redhat.com>]

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.
