ab7bc4e1a5 drm/i915: Unify the TypeC port notation in debug/error messages 
Unify the TypeC port notation in log messages, so that it matches the
spec. For instance the first ICL TypeC port will read as 'Port C/TC#1'.

v2:
- Format print the name only once. (José)

3b2ed43134 drm/i915: Don't enable the DDI-IO power in the TypeC TBT-alt mode 
According to the spec we should not enable the DDI-IO power domain if
the TypeC port is in the TBT-alt mode, so do that only in the other
TypeC modes or for non-TypeC ports. See the internal BSpec Index/22243.

v2:
- Add the internal BSpec reference to the log message. (José)

e9b7e1422d drm/i915: Sanitize the terminology used for TypeC port modes 
The TypeC port mode can switch dynamically, to reflect that better call
the port's mode as 'mode' rather than 'type'.

While at it:
- s/TC_PORT_TBT/TC_PORT_TBT_ALT/ and s/TC_PORT_TYPEC/TC_PORT_DP_ALT/.
  'TYPEC' is ambiguous, TBT_ALT and DP_ALT better match the reality.

- Remove the 'unknown' TypeC port mode. The mode is always known, it's
  the TBT-alt/safe mode after HW reset and after disconnecting the PHY.
  Simplify the tc_port/tc_type checks accordingly.

- Don't WARN if the port mode changes, that can happen normally.

No functional changes.

bc85328ff4 drm/i915: Move the TypeC port handling code to a separate file 
Move the TypeC port handling functions to a new file for clarity.

While at it:
- s/icl_tc_port_connected()/intel_tc_port_connected()/
  icl_tc_phy_disconnect(), will be unexported later.

- s/intel_dp_get_fia_supported_lane_count()/
    intel_tc_port_fia_max_lane_count()/
  It's used for HDMI legacy mode too.

- Simplify function interfaces by passing only dig_port to them.

No functional changes.

v2:
- Fix checkpatch issues: +1/-1 empty lines in intel_tc.c and add
  missing SPDX to intel_tc.h. (Jani)

379bc10023 drm/i915: move modesetting output/encoder code under display/ 
Add a new subdirectory for display code, and start off by moving
modesetting output/encoder code. Judging by the include changes, this is
a surprisingly clean operation.

v2:
- move intel_sdvo_regs.h too
- use tabs for Makefile	file lists and sort them
