staging: imx-drm: Replace DRM_LOG_KMS() by DRM_DEBUG_KMS()
There are only a few users of the DRM_LOG_KMS() macro. We can simplify
the DRM code a bit by replacing them by DRM_DEBUG_KMS().

drm: Refresh the explanation of debug categories
That comment wasn't super-readable, so I tried to improve it:
- Put the comment before the values it's documenting
- Add a mention to PRIME
- Reword things a bit to be a lighter read
- Add a note about the option to set the debug value at run-time

drm/nouveau: fix small thinko in vblank timestamping.
*hpos horizontal scanout position doesn't need to be corrected
to count the pixels between hactive end and htotal negative.
That is only needed for *vpos to count lines until end of
vblank for the vblank timestamping.
Use hpos as is without correction.
Removes occassional spikes in timestamps of up to 1 scanline
duration, thereby improves accuracy to about +/- 2 usecs instead
of +/- 12 usecs, wrt. true onset time as measured with high
precision equipment on NV-A5.

drm/nouveau/bios: add more checks to PRAMIN image fetching
Prevents an attempt to access VRAM on an un-posted board, which, on a
particular system with a GRID K1 installed, causes a MCE and chokes
the entire system.
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.
