drm/mipi-dbi: Add driver_private member to struct mipi_dbi_dev



devm_drm_dev_alloc() can't allocate structures that embed a structure
which then again embeds drm_device. Workaround this by adding a
driver_private pointer to struct mipi_dbi_dev which the driver can use for
its additional state.

v3:
- Add documentation
