[Intel-gfx] [PATCH 4/3] drm/i915: pass intel_crtc as argument for intel_enable_pipe

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

We want to remove those 3 boolean arguments. This is the first step.
The "pipe" passed as the argument is always intel_crtc->pipe.

Also adjust the function documentation.
