Ryu: Rewrite I2C6 mux init

Do the absolute minimum needed to allow the DPAUX mux ctl write
    for I2C6. This leaves HOST1X off (reset and clock disabled) to
    avoid a conflict with any kernel display driver init.

I2C6 init/enable will be moved to ramstage in the next CL.

BUG=chrome-os-partner:31820
    BRANCH=none
    TEST=Dumped Speaker Driver (AD SSM4567) regs on Ryu, looks good.
