Subject: [PATCH 0/5] gpio: Implement and utilize register structures for ISA drivers

The PC104/ISA drivers were updated to use I/O memory accessor calls such
as ioread8()/iowrite8() in a previous patch series [1]. This
patchset is a continuation of the effort to improve the code readability
and reduce magic numbers by implementing and utilizing named register
data structures.

One of the benefits is that we can now observe more easily similarities
in devices that share similar interfaces; such as the i8255 interfaces
used by the 104-DIO-48E, 104-IDI-48, and GPIO-MM drivers -- as well as
the similar interface used by the 104-IDIO-16 and PCI-IDIO-16 drivers. I
hope to consolidate some of these code blocks in future patchsets.
