drm/rockchip: drv: mv show logo after drm_dev registered

Browse Source 
execution of extcon_set_state_sync() within the DP driver’s
.loader_protect helper failed due to dp->audio->extcon not
being allocated in dw_dp_single_audio_init() yet, which resulted
in the audio not work when the power-on logo feature is enabled.
so mv drm_dev_register() before rockchip_drm_show_logo().

Call trace:
