[PATCH 37/51] drm/i915: Pull intel_pipe_set_base() out of the crtc_mode_set() functions

[ville.syrjala at linux.intel.com]

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

intel_pipe_set_base() (un)pins the buffers, so it can't be called from
the atomic modeset paths. Pull the intel_pipe_set_base() and watermark
modifications out of i9xx_crtc_mode_set() and ironlake_crtc_mode_set()
into intel_crtc_mode_set(), so that the former two can be used from the
atomic modeset paths.
