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.

drm/i915: Factor out common parts from TypeC port handling functions Factor out helpers reading/parsing the TypeC specific registers, making current users of them clearer and letting us use them later. While at it also: - Simplify icl_tc_phy_connect() with an early return in legacy mode. - Simplify the live status check using one bitmask for all HPD bits. - Remove a micro-optimisation of the repeated safe-mode clearing. - Make sure we fix the legacy port flag in all cases. Except for the last two, no functional changes. v2: - Don't do reg reads at variable declarations. (Jani) - Prevent constant truncated compiler warning when assigning the valid_hpd_mask. (Nick) - s/intel_tc_port_get_lane_info/intel_tc_port_get_lane_mask/ (Ville) v3: - Make valid_hpd_mask init clear.

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.
