Platforms without a HW detiler doesn't support the get_tiling IOCTL.
Fix the drm_intel_bo_gem_create_from_* functions assuming the default
no-tiling, no-swizzling setting for the GEM buffer in this case.

- Add the missing gem handle IOCTL parameter. (Eric)

Changes in v7:
* Set atomic state hooks explicitly
Changes in v3:
* Adjust things to match the new bus-format negotiation approach
* Use drm_atomic_helper_bridge
drm_bridge_state is extended to describe the input and output bus
configurations. These bus configurations are exposed through the
drm_bus_cfg struct which encodes the configuration of a physical
bus between two components in an output pipeline, usually between
two bridges, an encoder and a bridge,
Hello,
This patch series aims at adding support for runtime bus-format
negotiation between all elements of the
'encoder -> bridges -> connector/display' section of the pipeline.
In order to support that, we need drm bridges to fully take part in the
atomic state validation process, which requires
So that bridge drivers have a way to check/reject an atomic operation.
The drm_atomic_bridge_chain_check() (which is just a wrapper around
the ->atomic_check() hook) is called in place of
drm_bridge_chain_mode_fixup() (when ->atomic_check() is not implemented,
the core falls back on ->mode_fixup(),
