r8152: load the default MAC address
Except for RTL_VER_01, replace loading the MAC address from PLA_IDR with from PLA_BACKUP. The default MAC address may be modified by the other OS, so the PLA_IDR may be not the default MAC address. The data in the PLA_BACKUP address of the RTL_VER_01 may be destoryed, so load MAC address from PLA_IDR for RTL_VER_01. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.
