[PATCH v4 0/7] MR2568: win32u: Support setting the current mode using gdi_device_manager.

[Alexandros Frantzis (＠afrantzis)]

Update the gdi_device_manager API to enable drivers to set the current mode (along with the registry mode if not already set) in
UpdateDisplayDevices.

This changes also allows us to remove the driver code that manually changes the registry settings.
