[PATCH v3 6/9] drm/i915: Set crtc->name to "pipe A", "pipe B", etc.

[ville.syrjala at linux.intel.com]

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

v2: Fix intel_crtc leak on failure to allocate the name
    Use a local 'name' variable to make things easier
v3: Pass the name as a function arguemnt to drm_crtc_init_with_planes() (Jani)
