For now, only print their content for diffing, but also add the necessary
bits that can be used for more verbose output in the fugure.

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.
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

Right now, we only check for hardware DRRS support. But much more can be
done with it. Some day.

Stops the compiler warning about not checking the potential error return
from asprintf, which was a false positive anyway.

A few of the tools can be performed post-mortem from a different system,
so it is useful to be able to compile those tools on those foreign
systems. Obviously, any program to interact with the PCI device or talk
to GEM will fail on a non-Intel system.
