Pierre Moreau 703fa264b1 drm/nouveau: Display Nouveau boot options at launch
It can help to remove any ambiguity about which options were passed to Nouveau,
especially in case the user had some options set in /etc/modprobe.d/*.conf that
he forgot about, as they won't appear in a dmesg.

Ben Skeggs 0d48b58af3 drm/nouveau: hide sysfs pstate file behind an option again
No-one has yet had time to move this to debugfs as discussed during
the last merge window.  Until this happens, hide the option to make
it clear it's not going to be here forever.

Ben Skeggs a532da976f drm/nouveau/device: audit and version NVIF_CONTROL class and methods
The full object interfaces are about to be exposed to userspace, so we
need to check for any security-related issues and version the structs
to make it easier to handle any changes we may need in the future.

Ben Skeggs 967e7bde87 drm/nouveau: initial pass at moving to struct nvif_device
This is an attempt at isolating some of the changes necessary to port
to NVIF in a separate commit.

Alexandre Courbot 420b946977 support for platform devices
Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead
of PCI to which Nouveau is tightly dependent. This patch allows Nouveau
to handle platform devices by:

- abstracting PCI-dependent functions that were typically used for
  resource querying and page mapping,
- introducing a nv_device_is_pci() function that allows to make
  PCI-dependent code conditional,
- providing a nouveau_drm_platform_probe() function that takes a GPU
  platform device to be probed.

Core code as well as engine/subdev drivers are updated wherever possible
to make use of these functions. Some older drivers are too dependent on
PCI to be properly updated, but all newer code on which future chips may
depend should at least be runnable with platform devices.
