drm/vkms: Allow to configure multiple connectors
Add a list of connectors to vkms_config and helper functions to add and
remove as many connectors as wanted.

For backwards compatibility, add one enabled connector to the default
configuration.

A future patch will allow to attach connectors and encoders, but for the
moment there are no changes in the way the output is configured.

one cursor plane and NUM_OVERLAY_PLANES planes to the default
configuration.

drm/vkms: Add a validation function for VKMS configuration
As the configuration will be used by userspace, add a validator to avoid
creating a broken DRM device.

For the moment, the function always returns true, but rules will be
added in future patches.

drm/vkms: Extract vkms_config header
Creating a new vkms_config structure will be more complex once we
start adding more options.

Extract the vkms_config structure to its own header and source files
and add functions to create and delete a vkms_config and to initialize
debugfs.

Refactor, no functional changes.
