    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:
