At this point in time, <ide.h> provides the IDE_BUS macro and the
function prototype for ide_set_reset, which is used with IDE_RESET. The
only files which should include this header are the ones that either use
that macro or that function. Remove <blk.h> from <ide.h> and remove
<ide.h> from places which do not need it.
