As Arnd mentions in his reply, these are available everywhere. Also note, that as I've tried to explain in the commit message already this commit makes no functional changes what so ever, the generic musb_default_read/write_fifo functions are only used by musb platforms which do not overwrite musb_write* / musb_read* and musb_write* / musb_read* are already just thin wrappers around the __raw_* functions.
