ryu: audio: Enable RT5677 audio codec
Take codec out of reset (GPIO_PH1 aka CODEC_RST_L) and enable LDO2
(GPIO_PR2/KB_ROW2 aka AUDIO_ENABLE). Muxes are setup and the two
GPIOs are set to output and driven high.
BUG=chrome-os-partner:32582
BRANCH=none
TEST=RealTek ALC5677 codec shows up in I2C6 scan at address 0x2D,
can read/write registers.
