This reverts commit 301ad44cdf1b868b1ab89096721da91fa8541fdc.
When a render-only device is opened and gem_quiescent_gpu is called, we
need to use the debugfs dir for the master device instead.

When opening a DRM debugfs file, locate the right path based on the
given DRM device FD.
This is needed so, in setups with more than one DRM device, any
operations on debugfs files affect the expected DRM device.
v2: - rebased and fixed new API additions
v3: - updated chamelium test, which was missed previously
- use the minor of the device for the debugfs path, not the major
- have a proper exit handler for calling igt_hpd_storm_reset with the
right device fd.

Global variable names should reflect the fact that they are indeed
global, and at the very least they should not be as short as just
"mmio". Rename mmio to igt_global_mmio.

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.

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 ...

Makes their intent a bit clearer.

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.
