The Comedi "comedi_8254.h" header file is included by various Comedi drivers with timer/counters based on the 8254 chip. The drivers do not compile cleanly if this header file is included first. It uses pointers to the `struct comedi_device`, `struct comedi_subdevice`, and `struct comedi_insn` structures in various function prototypes, so declare those as incomplete types. It use the `bool` type, so include <linux/types.h>. It also uses the `__iomem` tag, but that seems to be taken care of indirectly by including <linux/types.h>.
