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.
