hwmon: (pmbus/tps53679) Add support for TPS53647 and TPS53667

Browse Source 
TPS53647 and TPS53667 are single channel, Step-Down Buck Controllers.
TPS53647 supports 4 phases, TPS53667 supports 6 phases.
The chips do not support per-phase output telemetry.

If you say yes here you get hardware monitoring support for TI
TPS53679, TPS53681, and TPS53688.
TPS53647, TPS53667, TPS53679, TPS53681, and TPS53688.
This driver can also be built as a module. If so, the module will
be called tps53679.
