drm/amd/display: Fix compound literal stackframe limit

Browse source

[Why]
Use of compound literals to initialize heap objects may create stack
temporaries when compiling in debug mode. For large objects such
as dc_memory_pool which is 2 pages large to avoid cacheline sharing,
this causes function stackframe to exceed kernel limit.

[How]
Replace compound literal with field-by-field initialization.
