Sprinkle in some BUILD_BUG_ON()s to make sure some of
the bitmasks used in the device info have enough bits.
Do we have a better place for this sort of stuff?
it's being moved to display/, so I'd say the intel_display_device_info.c
is a better place. What about using a static_assert() and leave them
near the top of the file?
