In a similar vein as the Intel 8255 interface library module [0], the
ACCES IDIO-16 GPIO library module is introduced to consolidate much of
the shared code between the existing 104-IDIO-16 and PCI-IDIO-16 GPIO
drivers.

The idio-16 module exposes consumer library functions to facilitate
communication with devices within the ACCES IDIO-16 family such as the
104-IDIO-16 and the PCI-IDIO-16.

A CONFIG_GPIO_IDIO_16 Kconfig option is introduced by this patch.
Modules wanting access to these idio-16 library functions should select
this Kconfig option and import the IDIO_16 symbol namespace.
