Subject: [PATCH 10/12] drm/i915/psr: automatic conversion to drm_device based logging macros.

Converts instances of the printk based logging macros to the struct
drm_device based logging macros in i915/display/intel_psr.c using the
following coccinelle script that transforms based on the existence of a
drm_i915_private device pointer:
