Revise Yosemite 4 devicetree for i2c-mux and eeprom,
also the following changes:
- Enable adc 15, tpm, wdt2
- Change spi-tx/rx-bus-width to duo mode
- Add device mp5023, pmbus for Flex power module
- Change ina230 to ina233, pca9846 to pca9546
- Set adc128d818 and max31790 config
- Add jtag1 and gpio0 config
