eth: fbnic: hwmon: Add support for reading temperature and voltage sensors

Add support for reading temperature and voltage sensor data from firmware
by implementing a new TSENE message type and response parsing. This adds
message handler infrastructure to transmit sensor read requests and parse
responses. The sensor data will be exposed through the driver's hwmon interface.
