Nathan Chancellor f580786ea9 staging: gpib: Make GPIB_NI_PCI_ISA depend on HAS_IOPORT 
After commit 78ecb03756 ("staging: gpib: make port I/O code
conditional"), building tnt4882.ko on platforms without HAS_IOPORT (such
as hexagon and s390) fails with:

  ERROR: modpost: "inb_wrapper" [drivers/staging/gpib/tnt4882/tnt4882.ko] undefined!
  ERROR: modpost: "inw_wrapper" [drivers/staging/gpib/tnt4882/tnt4882.ko] undefined!
  ERROR: modpost: "nec7210_locking_ioport_write_byte" [drivers/staging/gpib/tnt4882/tnt4882.ko] undefined!
  ERROR: modpost: "nec7210_locking_ioport_read_byte" [drivers/staging/gpib/tnt4882/tnt4882.ko] undefined!
  ERROR: modpost: "outb_wrapper" [drivers/staging/gpib/tnt4882/tnt4882.ko] undefined!
  ERROR: modpost: "outw_wrapper" [drivers/staging/gpib/tnt4882/tnt4882.ko] undefined!

Only allow tnt4882.ko to be built when CONFIG_HAS_IOPORT is set to avoid
this build failure, as this driver unconditionally needs it.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
