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

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.

Merge branch 'exynos-drm-next' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next

Highlights
----------

Re-factoring works over the exynos drm framework.
  - drm_crtc, drm_encoder/drm_connector are implemented by sub drivers
    directly.
  - Removing pm interfaces from each sub driver, and implementing them
    at top level of exynos drm.
Add DisplayPort Transmitter driver.
  - Just moving existing driver from drivers/vides/exynos into
    drivers/gpu/drm/exynos.
Add new LVDS bridge driver, PTN3460.
  - Placed in drivers/gpu/drm/bridge, and this device is used to transfer
    image signal from DP(DisplayPort) to LVDS Panel.
    So this driver will be used with DP driver moved into exynos drm.
Add parallel panel support
  - With the re-factoring patch series, existing parallel panel support was
    broken by moving exynos_drm_display ops into each real connector driver,
    DP. So this patch series adds a new parallel panel module,
    exynos_drm_dpi, for supporting parallel panel, and also adds relevant
    bindings.
Some fixups and cleanups.

drm/exynos: restore parallel output interface support

The patch adds parallel output interface to FIMD device driver.
It also restores support for panels initialized by boot loader,
but without proper kernel driver.
Driver uses video interface bindings to find connected panel.
It uses drm_panel interface to interact with the panel.

drm/exynos: delay fbdev initialization until an output is connected

In case fbdev is initialized before any output is connected,
fb resolution defaults to 1024x768. After that any output with
bigger resolution is ignored and fbdev is not displayed.
The patch postpones fbdev initialization to avoid such situation.
