iwlwifi: Temperature sensor voltage reading for 5150
The temperature measurement by uCode for 5150 and 5000 are different
CSR_HW_REV_TYPE_5150: temperature sensor output voltage
CSR_HW_REV_TYPE_5000: temperature in Celsius
temperature related operation for 5150 is measured by temperature sensor
output voltage; additional conversion is required for set and store
the temperature.
To make sure support different HW design; implement _ops method for
temperature related functions (temperature reading and set ct kill
threshold)
