Similar to what's done in kernel. It's a bit artificial that the parsing
and dumping are two separate steps in the userspace tool, but it's
easier to follow and debug the code when both the kernel and userspace
are similar.
v2: don't segfault so much on dumping null pointers

Due to the clever way the whole sequence block is specified without
forward compatibility, it's not possible to dump most blocks without
this.

Check that the offset where expect to find the device id is withing the
BIOS image, instead of accessing whatever (if anything) happens to be
there.

New stuff has been added to the end of the child device block at various
times, so using a hardcoded size for the block is a bad idea.
Fortunately the size of the block is listed in the VBT just before the
blocks themselves, so grab it from there.

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.

We still need to dump some of the known sections explicitly due to
dependencies on information extracted, such as LFP data pointers and
panel_type.

Dump sections through a table based on the section id.
Hex dump the section. This works also for unknown sections.

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.

Some of our device class defines were incorrect, and we were missing
several recent ones, so fix those up and dump more child device data if
we have it.
Actually, fix to work on _any_ machine where the ROM file doesn't match
the GPU. Just extract the device ID from the ROM itself rather than
look at the running system.
