For Lunar Lake, DDI-A is connected to C10 PHY, while TC1-TC3 are connected to C20 phy, like in Meteor Lake. Update the check in intel_is_c10phy() accordingly. This reverts the change in commit e388ae97e225 ("drm/i915/display: Eliminate IS_METEORLAKE checks") that turned that into a display engine version check. The phy <-> port connection is very SoC-specific and not related to that version. IS_LUNARLAKE() is defined to 0 in i915 as it's expected that the (upcoming) xe driver is the one defining the platform, with i915 only driving the display side.
