mlxsw: thermal: Add function for reading module temperature and thresholds

Browse source

Provide new function mlxsw_thermal_module_temp_and_thresholds_get() for
reading temperature and temperature thresholds by a single operation.
The motivation is to reduce the number of transactions with the device
which is important when operating over a slow bus such as I2C.

Currently, the sole caller of the function is only using it to read the
module's temperature. The next patch will also use it to query the
module's temperature thresholds.
