tg3: replace placeholder MAC address with device property
On some systems (e.g. iMac 20,1 with BCM57766), the tg3 driver reads
a default placeholder mac address (00:10:18:00:00:00) from the
mailbox. The correct value on those systems are stored in the
'local-mac-address' property.
This patch, detect the default value and tries to retrieve
the correct address from the device_get_mac_address
function instead.
The patch has been tested on two different systems:
- iMac 20,1 (BCM57766) model which use the local-mac-address property
- iMac 13,2 (BCM57766) model which can use the mailbox,
NVRAM or MAC control registers
