[PATCH v3 00/16] drm/vkms: Introduce detailed configuration

[Louis Chauvet <louis.chauvet@bootlin.com>]

The current code is not flexible to configure the VKMS device. In
preparation for ConfigFS interface introduce few structure that can be
used to configure the device creation: `vkms_config`.

This part is splitted from the ConfigFS implementation itself to avoid
mixing two complex interfaces.

The vkms_config structure will allows the configuration of:
- planes
    - name
    - possible_crtcs
    - supported_rotations
    - default_rotation
    - type
    - format
- crtcs
    - name
    - possible_planes [automatically filled by helpers]
    - possible_encoders [automatically filled by helpers]
- encoders
    - name
    - type
    - possible_crtcs
- connectors:
    - type
    - status
    - EDID

Changes in v3:
- Remove the plane color encoding/range and not yet supported formats so 
  it does not have any dependencies
- Created a helper to get config for a connector
- Rebased on drm-misc-next
- Link to v2: https://lore.kernel.org/r/20241122-google-remove-crtc-index-from-parameter-v2-0-81540742535a@bootlin.com

Changes in v2:
- Rebased on drm-misc-next
- Added support for many new configuration
- Link to v1: https://lore.kernel.org/r/20240814-google-remove-crtc-index-from-parameter-v1-0-6e179abf9fd4@bootlin.com
