Subject: [PATCH v10 0/2] Add tps53685 support

The TPS53685 is a fully AMD SVI3 compliant step down controller with
trans-inductor voltage regulator(TLVR) topology support, dual channels,
built-in non-volatile memory (NVM), PMBus interface, and full compatible
with TI NexFET smart power stages.

Add support for TPS53685 device to dt-bindings and pmbus driver.

- Use existing tps53679_identify_multiphase() with argument 
  "TPS53685_DEVICE_ID" in tps53685_identify() rather than creating one 
  tps53685_identify_multiphase()
