In particular the PMU clock for port 2 must be surely ungated before accessing the REG_HCI_PHY_CTL register of port 2. To allow each USB port to be controlled independently of port 2, we need a handle to that particular PMU clock in the *PHY* node, as the HCI and PHY part might be handled by separate drivers. Add that clock to the requirements of the H616 PHY binding, so that a PHY driver can apply the quirk in isolation, without requiring help from port 2's HCI driver.
