Hi All,
This is a follow up in my long running effort of making inb()/outb() and
similar I/O port accessors compile-time optional. After initially
sending this as a treewide series with the latest revision at[0]
we switched to per subsystem series. Now though as we're left with only
5 patches left

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. As hexagon does not support I/O port access it also
the GENERIC_IOMAP mechanism of dynamically choosing between I/O port and
MMIO access doesn't work so don't select it.

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them. In the bochs driver there is optional MMIO support
detected at runtime, warn if this isn't taken when HAS_IOPORT is not
defined.

With all subsystems and drivers either declaring their dependence on
HAS_IOPORT or fencing I/O port specific code sections we can finally
make inb()/outb() and friends compile-time dependent on HAS_IOPORT as
suggested by Linus in the linked mail. The main benefit of this is that
on platforms such a
