drm/rockchip: dsi2: optimize drive probe process

Browse Source 
Put "component_add" in the attach call so that dsi host and dsi device
(panel or bridge) can be regarded as a component as a whole.

dsi calls "mipi_dsi_host_register" so that the panel executes the probe
process or the bridge successfully executes "mipi_dsi_device_register_full"
during the probe process. The panel or bridge triggers "component_add"
by calling mipi_dsi_attach after the probe is successful.

Through the above modifications, you can avoid dsi defer probe infinitely
due to panel configuration errors.
