[PATCH v4 21/41] parport: PC style parport depends on HAS_IOPORT

[Niklas Schnelle]

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. As PC style parport uses these functions we need to
handle this dependency.

Note: The HAS_IOPORT Kconfig option was added in v6.4-rc1 so
      per-subsystem patches may be applied independently
