From: Arnd Bergmann <arnd@xxxxxxxx>
The graphics_object_id structure is meant to fit into 32 bits, as it's
passed by value in and out of functions. A recent change increased
the size to 128 bits, so it's now always passed by reference, which
is clearly not intended and ends up producing a compile-time warning:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c: In function 'construct_phy':
drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c:743:1: error: the frame size of 1040 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Add back the bitfields to revert to the original size, while keeping
the 'enum' type change.
