Subject: [PATCH 01/12] drm/i915/vlv_dsi_pll: conversion to struct drm_device logging macros.

Convert the printk based logging macros to the new struct drm_device
based logging macros in i915/display/vlv_dsi_pll.c using the following
coccinelle script that matches based on the existence of a drm_i915_private
device:

identifier fn, T;

Checkpatch warnings were fixed manually.
