We need to hold forcewake lock in order to be able to read GT registers.
Otherwise, when the GPU is in RC6 mode, we'll read all zeros.

We should get more kms tests soon, and not needing to copy-paste a
nice test pattern should be useful.
That establishes a firm depency of i-g-t on cairo over everything, but
I don't care so much about that.

This allows to specify '-d' parameter which will decode individual bits in
each register being read.
The register bits are printed horizontally for space reasons. This
requires more than 80x25 terminal to see them all. An alternative solution
would be to print them vertically, but this will become much more
difficult to read when printing multiple registers at the same time.
v2: fix spacing to get us a bit closer to the code nirvana.

The registers must be passed on the command line and will be read
sequentially, one at a time.

I was interested in finding why my IVB system is not getting GPU turbo
after suspend/resume. The piece that looks weird to me is that
INTERRUPT_THRESHOLD is sitting at 0, whereas pre-suspend it's
0x12000000.
The tool allows you to change the panel fitter settings, so you can
change the size of the screen being displayed on your monitor without
changing the real pixel size of your desktop. The biggest use case for
this tool is to work around overscan done by TVs and some monitors in
interlaced mode.
v2: reviews by Ben, Chris and Rodrigo
- don't install
- use intel_register_access_init
- check for maximum X and Y values
- add a disclaimer saying this is not the real solution
- print less when pf is disabled and option '-l' is used

Before this patch, handling dump files was wrong:
- when HAS_PCH_SPLIT was specified, intel_reg_dumper segfaulted inside
intel_check_pch()
- the "devid" variable was used but not set
- there was no way to specify the device id of the machine used to
generate the dump file
This patch fixes this behavior with the following changes:
- the HAS_PCH_SPLIT variable is gone
- there is now a '-d' argument that can be used to specify the device id
used to interpret the results
- when a dump file is used but the '-d' argument is not provided, an
Ironlake machine is assumed

Running intel_bios_reader upon itself causes the reader to crash and
burn. It obviously finds a VBT signature inside the binary, but then
does not rigorously check that all data blocks are valid before
dereferencing them.

Note that a per-ring error decode state would make more sense - this
way we could better decode the ring head and tail. But our current
head tracking is already lame (we need the kernel to also dump the
ringbuffer head/tail first, not just acthd), so I didn't bother.
