drivers/gfx/generic: Add _PLD support to GFX device
Add _PLD support to GFX device so that each display output can store
its physical location of connection point. This is to be used primarily
for describing DP on USB-C ports in the future patches.
The upstream Linux kernel now has a feature to compare _PLD of Type C
connectors and DP connectors to link them together.
https://cgit.freedesktop.org/drm/drm-misc/commit/?id=c5c51b2420625faa1f0e363f21dba1de53806ff7
This feature allows us to tell which display output is used by which
USB-C port.
So, for the future boards, we want to add _PLD for each DP connector
matching with the corresponding USB-C port.
