[Nouveau] [PATCH v2 0/3] drm/nouveau: support for probing platform devices

[Alexandre Courbot]

This series adds support for probing platform devices on Nouveau, as well as
the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since
a few extra things need to be supported before that.

Thanks to the input received for v1, this version is more self-contained and
shares less stuff between nouveau_drm and nouveau_platform. The major change
is that nouveau_platform is now a module of its own. The main reason for this
is that it allows us to register/unregister the driver from the module init
functions instead of parasiting the ones of nouveau_drm. It also makes it
simpler to build Nouveau without platform support at all.

Changes since v1:
* Moved the platform device driver to its own module. This allows it to be more
  self-contained and saves us the need to export too many functions from
  nouveau_drm and nouveau_platform.
* Register the DRM device without using the platform helpers, which is made
  possible by drm_dev_set_unique(). This allows us to catch and register the
  DRM device during platform probe.
* Fixed the clock names in the DT bindings.
* Removed the patches enabling GK20A on Venice2 and Jetson TK1 as support
  is not complete yet.
