Subject: [PATCH 0/8] Utilize iomap interface for PC104 and friends

PC104 cards and similar devices do not need to access I/O ports directly
via inb()/outb() and can instead use the more typical I/O memory
ioread8()/iowrite8() accessor calls by first calling ioport_map(). This
patchset converts the relevant PC104/ISA card drivers to do such. With
these drivers now utilizing I/O memory accessor calls, work can be done
to consolidate some similar devices (e.g. 104-idio-16, pci-idio-16,
etc.) into a unified driver in a future patchset.

This patchset spawned from a suggestion made in another thread titled
"gpio: add HAS_IOPORT dependencies":
