drm/tyr: rename pad0 to selected_coherency
This applies the uapi change in commit ea78ec982653 ("drm/panthor:
Expose the selected coherency protocol to the UMD") to the Tyr driver as
well.
Once this is merged with drm-rust-next, this kind of change to the uapi
struct is automatically reflected in the Tyr driver's GpuInfo. [1]
