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) Change-Id: I93f3917c19cc3f0f8fd7b5e1b4d9b24a59f45f84 Signed-off-by: Sathya Prakash M R <sathya.prakash.m.r@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/31280 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
