comedi: add HAS_IOPORT dependencies again


In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.

This was previously done in commit b5c75b68 ("comedi: add HAS_IOPORT
dependencies"), but that has been reverted because it made it impossible
to select configuration options for several comedi drivers.  This is a
do-over that avoids that.

Since the original patch, modifications have been made to various comedi
modules so that they can still be built even if the port I/O functions
have not been declared, so the configuration options for building those
modules no longer need to depend on HAS_IOPORT.

Make the COMEDI_ISA_DRIVERS menu option (which allows configuration
options for ISA and PC/104 drivers to be selected) depend on HAS_IOPORT,
and also depend on ISA || ISA_BUS || PC104.
