USB: EHCI: msm: Configure GPIOs for HSIC strobe and data lines
As part of HSIC initialization, in addition to enabling HSIC host
mode and periodic pad calibration, need to configure GPIO150 and
GPIO151 pins for HSIC strobe and data lines respectively for
proper data communication between HSIC devices.
