Kconfig cleanup (PARPORT_PC dependencies)

Remove messy dependencies from PARPORT_PC by having it depend on one
Kconfig symbol (ARCH_MIGHT_HAVE_PC_PARPORT) and having architectures
which need it, select ARCH_MIGHT_HAVE_PC_PARPORT in arch/*/Kconfig.
New architectures are unlikely to need PARPORT_PC, so this avoids
having an ever growing list of architectures to exclude. Those
architectures which do select ARCH_MIGHT_HAVE_PC_PARPORT in this
patch are the ones which have an asm/parport.h (or use the generic
version).

          You should say Y here if you have a PC-style parallel port. All
