drm/i915: hide unused intel_panel_set_backlight function

commit fd94d53e55bd487368dfee9f1af24da78b2bb582 upstream.

Building i915 without backlight support results in a harmless warning
for intel_panel_set_backlight:

drivers/gpu/drm/i915/intel_panel.c:653:13: error: 'intel_panel_set_backlight' defined but not used [-Werror=unused-function]

This moves it into the CONFIG_BACKLIGHT_CLASS_DEVICE section that
its caller is in.
