The PC parallel port Kconfig as acquired one of those messy terms to

This isn't just ugly - it also almost certainly describes the dependencies
too coarse grainedly.  This is an attempt at cleaing the mess up.

I tried to faithfully aproximate the old behaviour but the existing
behaviour seems inacurate if not wrong for some architectures or platforms.
To improve on this I rely on comments from other arch and platforms
maintainers.  Any system that can take PCI multi-IO card or has a PC-style
parallel port on the mainboard should probably should now do a
select HAVE_PC_PARPORT.  And some arch Kconfig files should further
restrict the use of HAVE_PC_PARPORT to only those platforms that actually
need it.

Why on earth restrict it like that?  It's just a device driver, like
more or less any other device driver...
