board-8960: Add HSUSB PHY Init Sequeunce for SGLTE Platform
Due to availability of Switch on SGLTE Platform to route Modem
or 8960 HSUSB signals on same port, few compliance test like device
mode eye diagram test and EL_27 are failing. Hence it is required to
have different HSUSB PHY setting than 8960. Add HSUSB PHY setting
recommended for SGLTE Platform which is fixing above mentioned
compliance failure.
