drm/i915/display: Extend i915_display_info with Type-C port details
Expose key Type-C port data in i915_display_info to make it easier to
understand the port configuration and active mode, especially whether
the link is in DP-Alt or TBT-Alt, without having to scan kernel logs.
Tested in DP-Alt, TBT-Alt, SST, and MST.
Expected output:
[CONNECTOR:290:DP-2]: status: connected
TC Port: E/TC#2 mode: tbt-alt pin assignment: - max lanes: 4
physical dimensions: 600x340mm
...
[CONNECTOR:263:DP-5]: status: connected
TC Port: G/TC#4 mode: dp-alt pin assignment: C max lanes: 4
physical dimensions: 610x350mm
v2: Use drm_printer (Ville)
Lock/Unlock around the printf (Imre)
v3: Forward Declaration drm_printer struct (Jani)
v4: Handle MST connector with no active encoder (Imre)
Add a delimiter between fields and ":" after the port name (Imre)
v5: Init dig_port and use it in intel_encorder_is_tc and tc_info (Imre)
Move tc->port_name to a newline (Imre)
v6: Use intel_tc_port_lock/Unlock (Imre)
