usb: phy: msm: Fix PTS definitions for MSM USB controller

Browse Source 
Fix the value used for Parallel Transceiver Select (PTS) for the MSM USB
controller.  This is a standard chipidea PORTSC definition, where
a PHY_TYPE of 10b (<<30) is ULPI and 11b (<<30) is SERIAL.
Fix the definitions and use them correctly in the driver code.
