[Intel-gfx] [PATCH v3 01/10] drm/i915: Set crtc_state->lane_count for HDMI

[Ander Conselvan de Oliveira]

Set the lane count for HDMI to 4. This will make it easier to
unduplicate CHV phy code.

v2: Set lane_count in *_get_config() to please state checker. (0day)
v3: Set lane_count for DDI in DVI mode too. (CI)
