[PATCH RFC v2 00/18] drm/vkms: Introduce detailed configuration

[Louis Chauvet]

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_color_encodings
    - supported_rotations
    - supported_color_ranges
    - default_rotation
    - default_color_range
    - default_color_encoding
    - 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
