UCSI connector's indices start from 1 up to 3, PMIC_GLINK_MAX_PORTS.
Correct the condition in the pmic_glink_ucsi_connector_status()
callback, fixing Type-C orientation reporting for the third USB-C
connector.

Fixes: 76716fd5bf09 ("usb: typec: ucsi: glink: move GPIO reading into connector_status callback")
