Export headless sku bit (bit 13) from opregion->header->pcon as an
interface to check if our device is headless configuration.
This is mainly targeted for hybrid gfx systems. E.g. when display
is not supposed to be connected discrete graphics card it's
opregion can inform this is headless graphics card.
v3: Dummy version is now static inline function
v2: Check also opregion version

The ACPI OpRegion Mailbox #5 ASLE extension may contain an EDID to be
used for the embedded display. Add support for using it via by adding
the EDID to the list of available modes on the connector, and use it for
eDP when available.
If a panel's EDID is broken, there may be an override EDID set in the
ACPI OpRegion mailbox #5. Use it if available.
Fixes the GPD Win Max display.

Now that we have a new subdirectory for display code, continue by moving
modesetting core code.
display/intel_frontbuffer.h sticks out like a sore thumb, otherwise this
is, again, a surprisingly clean operation.
v2:
- don't move intel_sideband.[ch] (Ville)
- use tabs for Makefile file lists and sort them
