Servo: Adds persistent storage of MAC address
Adds a field to the persistent storage to store the
MAC address of the device. This is enabled on ServoV4
in order to store the MAC address for the integrated
ethernet port. Added a console command to set and load
this value.
BUG=b:149506580
TEST=Verified setting and loading the MAC address using:
'macaddr set 12:34:56:78:90:ab' and 'macaddr' or 'macaddr load'
Verified that MAC addresses over 19 characters long return
an error response and not update the MAC.
Verified no set serial number will return the uninitialized string.
Verified that the MAC address can be updated independently of serialno
Verified that the persist_state fields restore during firmware updates
