drm/i915/display: Add definition for wcl as subplatform

Browse Source 
We will need to differentiate between WCL and PTL in
intel_encoder_is_c10phy(). Since WCL and PTL use the same display
architecture, let's define WCL as a subplatform of PTL to allow the
differentiation.

v2: Update commit message and reorder wcl define (Gustavo)

Fixes: 3c0f211bc8 ("drm/xe: Add Wildcat Lake device IDs to PTL list")
