drm/i915/dp: Introduce helpers to enable/disable CMN SDP Transmission line

Browse source

Introduce helpers to program or disable CMN_SDP_TL and stagger registers
using the state stored in crtc_state.

v2:
- Use HAS_COMMON_SDP_TL(display) instead of checking
  crtc_state->dip.cmn_sdp_tl, since 0 is a valid transmission line value.
  (Sashiko)
