drm/i915: split fb allocation and initialization v2
If we use a stolen buffer, our probe callback shouldn't allocate a new
buffer; we should re-use the one from the BIOS instead if possible.
v2: fix locking (Jesse)
Bug detailed description:
-----------------------------
Igt/gem_render_copy causes gpu hangs.
This is the first time to run igt test on Broadwell.
Error log:
[ 186.649624] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 186.649715] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 186.652134] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 186.654378] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 186.656653] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
Steps:
---------------------------
./gem_render_copy</pre>
