phy: msm: usb: Fail suspend if psy_type is USB or USB_CDP

Currently driver is checking only charger type from internal variable
in msm_otg_suspend(), which is valid for PHY based charger detection.
If PMIC charger does charger detection, that charger type will not be
updated and result in allowing low power mode sequence even VBUS is
active. Hence fix it by checking psy_type as well to avoid allowing
low power mode sequence while VBUS is active.
