i945/gma.c: Generate fake VBT
This generates a fake VBT for the Intel i945 graphic device. i945
supports both the mobile chipset 945gm (calistoga) and the desktop
chipset 945gc (lakeport), which is why a VBT with a different id string
needs to be created for each target.
The VBT id string is obtained from the vbios blob in the following way:
"strings vbios.bin | grep VBT".
