meta-ampere: Set BMC MAC Address from FRU inventory

Support to get BMC MAC address from FRU over the FRU inventory
information (/xyz/openbmc_project/inventory/system/chassis/motherboard)
and update to the eth0 Ethernet interface and set the eth1addr u-boot
variable.

Tested:
1. Boot to u-boot, clear the eth1addr variable, save and reboot.
2. Boot to Linux:
 - Check if the eth0 interface uses the MAC address in FRU.
    root@mtjade:~# ip addr show dev eth0
    2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
        link/ether 70:e2:84:86:76:ba brd ff:ff:ff:ff:ff:ff
 - Check if the eth1addr u-boot variable uses the MAC address in FRU
    root@mtjade:~# fw_printenv eth1addr
    eth1addr=70:E2:84:86:76:BA
