intel_dp_aux_supports_hdr_backlight() prints debug message for intel HDR backlight version. This is fine when dealing with eDP 1.4b and lower. When we are talking about eDP 1.5 it causes confusion in logs since we need to use VESA AUX backlight functions but this print causes confusion as to which path code take. Short circuit this function with a eDP version check. Make sure this is only called if eDP <= 1.4b
