[SRU][R][PATCH v2 09/12] drm/i915/backlight: Update debug log during backlight setup

[Werner Sembach]

From: Suraj Kandpal <suraj.kandpal at intel.com>

With luminance_set which represents PANEL_LUMINANCE_OVERRIDE, we
have another variable to decide if we use PWM or DPCD.
Make drm_dbg_kms log represent that.
