[PATCH v2 16/21] drm/i915/dp: Allocate/free DP tunnel BW in the encoder enable/disable hooks

[Imre Deak <imre.deak@intel.com>]

Allocate and free the DP tunnel BW required by a stream while
enabling/disabling the stream during a modeset.

v2:
- Move the allocation up from encoder hooks to
  intel_atomic_commit_tail().
