The devfn field in the IOSF SB messages is only relevant when there's a
real PCI bus or some other multifunction device behind a single port.
Otherwise the port number itself is enough to uniquely identify the
target. In fact some IOSF SB targets reject the access when devfn is not
0.0 (eg. GPIO_NC on BYT).

Various stuff all over. Most done with the igt.cocci spatch, but
with a few fixups by hand. And add igt_core.h includes where needed.

Add generic tools to poke at IOSF sideband. The user needs to
manually specify SB port as well as the register.
TODO: Maybe add symbolic names for the units? Would avoid having
to trawl the docs for the magic hex value.

These opcodes are not specific for an endpoint, but are the same for all
endpoints. So rename them accordingly, using the name the VLV2 sideband
HAS uses. Also move the macros to the .c file, since they aren't used
anywhere else.

As usual de-inline functions for gtkdoc to see them.
I've decided to exclude the register map stuff since that's not
terribly interesting.
Aside: gtkdoc falls over when the title of a section contains a slash,
hence why it reads "IO" instead of "I/O". The fun ...

With the header cleanup we can now give this header a suitable name,
since it now really only contains register access and other I/O
functions and assorted definitions.

Only include what the header itself needs. The big fish here is
intel-gpu-tools.h. More will follow.
One ugly thing removed here is the duplicated GEN6_TD_CTL #define, one
of which was broken.

This makes it a bit more like the kernel, so we can go poke at DPIO and
other IOSF regs a bit more easily.
