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
Bspec: 53441
