meta-ampere: mtmitchell: ipmi-oem: configure bus-address of BMC's FRU

This commit configures the bus and address of the BMC FRU device
so that IPMI OEM commands can identify such.

Tested:
      1. Request to update MAC address.
         ipmitool raw 0x3c 0x01 0x70 0xe2 0x84 0x86 0x76 0xc0
      2. Reboot then check MAC address.
         ip a
      3. MAC address is updated as step 1.
