Subject: [PATCH] platform/chrome: cros_ec_typec: Decouple cable remove on disconnect

Type C cable objects are independent of partner objects. Don't return
if a partner object is not registered (mostly in the case of an error
while registering a partner), and instead treat the removal of partner
and cable objects on disconnect independently.

This patch should be applied on top of the series[1] which adds support
for cable & plugs to cros-ec-typec.
