google/chell: Update mainboard for EVT

- Disable kepler device, it is removed and was not used on proto anyway.
- Enable GPP_D22 as GPO to control I2S2 buffer for bit-bang PDM.
- Disable HS400, this is breaking some devices on proto boards and
is being disabled to reduce risk for EVT build.
- Change Type-C USB2 port drive strength.
