[v2,2/3] drm/mipi-dbi: Add driver_private member to struct mipi_dbi_dev

Commit Message

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.
