mb/google/hatch: Enable Audio support
Following changes are done to enable Audio support on hatch
1. Enable I2C4 device at 400Khz at 3.3V
2. Configure GPIO for HP INT and SPEAKER EN
3. Add ACPI entry for RT5682
4. Enable DMIC, I2S0 and I2S1 lines.
BUG=b:123738217
BRANCH=none
TEST=check SSDT table for RT5682 entry.
verify audio over SOF.
