Subject: [PATCH] drm/amd/display: Use context parameters to enable FBC

FBC fails to get enabled when switched between LINEAR(console/VT) and non-LINEAR(GUI) based rendering due to default value of tiling info stored in the current_state which is used for deciding whether or not to turn FBC on or off.

Use context structure's tiling information which is coherant with the screen updates.
