meta-ampere: mtmitchell: ipmi: support on-board sensor report

Support to report sensor information via IPMI for on-board sensors

Tested:
1. Check sensor report using IPMI sdr command:
$ ipmitool sdr list
OutletTemp       | 28 degrees C      | ok
Psu1InletTemp2   | 32 degrees C      | ok
PcieZoneTemp1    | 30 degrees C      | ok
Psu0InletTemp2   | 29 degrees C      | ok
PcieZoneTemp2    | 28 degrees C      | ok
