ARM SCMI updates/fixes for v5.3

Browse source 
1. Correction to ARM document ID referred in SCMI protocol binding
 2. Fix to correct bitfield definitions for SENSOR_DESC attributes which
    otherwise will calculate sensor values on wrong scale
 3. Adds the missing rate_discrete flag setting so that discrete clocks
    are handled correctly. Without this fix it assumes continuous range
    which is incorrect
 4. Adds support to read and scale the sensor values based on the factor
    read from the firmware
