drm/i915: Fix pipe enabled mask for pipe C in WM calculations
Fix the incorrect enabled pipes mask for pipe C in the WM calculations.
Additionally, in an effort to make the code easier to understand,
populate the mask with 1 << PIPE_[ABC] instead of raw numbers.
v2: Use 1 << PIPE_[ABC] (ickle/danvet)
v3: Pass PIPE_[ABC] to g4x_compute_wm0() (ickle)
