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.
