drm/i915: Make skl_compute_dbuf_slices() behave consistently for all platforms

Currently skl_compute_dbuf_slices() returns 0 for any inactive pipe on
icl+, but returns BIT(S1) on pre-icl for any pipe (whether it's active or
not). Let's make the behaviour consistent and always return 0 for any
inactive pipe.
