2015-03-28Ryu: Rewrite I2C6 mux initTom Warren
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.

2015-03-27tegra132: Add special I2C6 initTom Warren
I2C6 has a special mux in the SOR/DC domain, so there's a ton of devices that need to be clocked, SOR unpowergated, and then the I2C6 muxing done in the DPAUX_HYBRID_PADCTL register.
