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.

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

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
