[PATCH] phy: google-usb: Fix runtime PM cleanup on probe failure

[Felix Gu]

In google_usb_phy_probe(), if typec_switch_register() fails,
pm_runtime_disable() is not called, leading to an unbalanced
runtime PM state on probe failure.

Switch to devm_pm_runtime_enable() to ensure that runtime PM is
automatically disabled both on probe failure and during driver
removal.
