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.
