[PATCH] platform/chrome: cros_ec_typec: deferred probe when typec count mismatch

[Ruihai Zhou]

The kernel bootup is much faster with normal mode. In this case,
there is a chance that the cros-ec-typec module get the actual typec
port counts but not accurate from ec before ec is able to setup it.
It will block the HDMI mux function.
Hence, return -EPROBE_DEFER to put the device onto the deferred probe
list when the typec count mismatch between ec and node.
