[PATCH 0/7] drm/msm: rework the ties between KMS and GPU parts of the driver

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

Currently the KMS and GPU parts of the msm driver are pretty much
intertwined. It is impossible to register a KMS-only device and
registering a GPU-only DRM device requires modifying the DT.  Not to
mention that binding the GPU-only device creates an interim platform
devices, which complicates IOMMU setup.

Rework the driver:
- Make it possible to disable KMS parts (if MDP4, MDP5 and DPU drivers
  are disabled).
- Register GPU-only devices without an interim platform device.
- Add module param that makes msm driver register GPU and KMS devices
  separately.
