drm/i915/vrr: Disable DC balance by default

Browse source

Disable VRR DC balance by default due to timing issues observed on some
panel/TCON combinations.

Keep the module parameter to enable DC balance during debugging and to
isolate DC balance effects from underlying VRR/display timing issues.

--v2:
- Make enable_dc_balance a bool and keep it disabled by default; fix the
  parameter type/value mismatch and correct the description (Chaitanya
  Kumar Borah, Jani Nikula)
- Explain in the commit message why the feature is gated and why a
  module parameter is used (Jani Nikula)

--v3:
- Commit message update (Jani Nikula)
