Currently we have a mix of static and dynamic information stored in
the display info structure. That makes it rather difficult to repopulate
the dynamic parts when a new EDID appears. Let's make life easier by
splitting the structure up into static and dynamic parts.
The static part will consist of subpixel_order, panel_orientation,
and bus_formats.
Actually I'm not sure where bus_formats & co. fit in all this. For some
drivers those seem to be static, even though they might fill them out
from .get_modes(). For other drivers this stuff even gets frobbed at
runtime, making it more some kind of a bastard encoder/connector state.
I'll just stick it into the static side so that the behaviour doesn't
change when I start clear out the entire dynamic state with memset().

The sii902x driver sets the bus_formats in get_modes, but it's a fixed
value and we may as well do it in bridge's attach op.
For the bridge drivers:
