[PATCH 00/17] drm/i915: Split driver init step to phases

[Imre Deak <imre.deak@intel.com>]

This is v2 of [1]. I addressed the comments from Chris and Jani. The
bulk of the change compared to v1 stems from Chris' idea to split the
different init steps into separate functions. This required some further
code shuffling as a preparation, hence the additional patches.

In the end driver load error path and dirver unload function became much
clearer. The init steps on the modesetting path would still need
to be moved to one of the new init phases functions according to the
role/effect of the given init step, but I left this for later.

Smoke tested on Gen4, SNB, IVB, BXT.
