[Intel-gfx] [PATCH 1/2] drm/i915: Print the pipe control page GTT address

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

We already print the HWS addresses during init, so do the same for the
pipe control page. Reduces guesswork when looking at hex addresses
later.
