[PATCH 5/8] drm/i915/backlight: Short circuit intel_dp_aux_supports_hdr_backlight

[Suraj Kandpal <suraj.kandpal@intel.com>]

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
