usb: typec: ps883x: fix missing accessibility check

Browse source

Make sure that the retimer is accessible before registering to avoid
having later consumer calls fail to configure it, something which, for
example, can lead to a hotplugged display not being recognised:

	[drm:msm_dp_panel_read_sink_caps [msm]] *ERROR* read dpcd failed -110
