To enable DisplayPort on the platforms supported by qcom-pmic-typec
driver, we need to register a corresponding drm_bridge for this device
and also be able to send the OOB hotplug event to the corresponding DRM
connector. All this is implemented by [1], but there is no direct
dependency on that patchset.

[1] https://patchwork.freedesktop.org/series/120393/

Changes since v3:
- Fixed changelog for v1 (Guenter)
- After discussion on IRC, change connector type to
  DRM_MODE_CONNECTOR_DisplayPort to follow i915 and amdgpu example.
  The fact that this is a DP wrapped in the USB connector will be
  handled separately via the subconnector property (Simon Ser, Janne
  Grunau)

Changes since v2:
- Reworded commit message for the first patch to explicitly mention that
  the "displayport" OF property was rejected (Bjorn)
- Removed several #ifdefs from the qcom-pmic-typec patch (Bryan, Konrad,
  Greg K-H)

Changes since v1:
- Properly handle CONFIG_DRM dependency. Disallow building
  qcom-pmic-typec into the kernel if DRM is built as module (Bryan).
