[PATCH] gpio: pc104: Add COMPILE_TEST coverage

[Rosen Penev]

The port-mapped GPIO drivers are hidden on non-x86 builds even when the
architecture provides I/O port access. Several PC/104 GPIO drivers only
depend on generic ISA, regmap, and gpiolib infrastructure, so they can be
built for compile-test coverage.

Allow the port-mapped GPIO menu and the PC/104 GPIO drivers to be selected
under COMPILE_TEST while retaining the existing HAS_IOPORT guard.
