msm: 8226: add support for HSIC 



Add the required gpiomux configurations for HSIC strobe and data
lines. HSIC strobe gpio is also used by the ethernet. Install
HSIC gpiomux configurations only when HSIC driver is enabled.
Ethernet will be disabled by default. HSIC config must be turned
off to enable the ethernet.
