mb/google/hatch: Enable audio support

Following changes are done to enable audio support on hatch
1. Enable I2C4 device at 400Khz at 1.8V
2. Configure GPIO for HP INT and SPKR_PA_EN
3. Add ACPI entry for RT5682 and MAX98357A
4. Enable I2S0 and I2S1 lines
5. Enable generic max98357a driver in Kconfig

BUG=b:123738217
BRANCH=none
TEST=Check SSDT table for RT5682 & MAX98357a entry.
     Verify audio using Sound Open firmware (SOF)
