hw/net/e1000: Remove unused E1000_FLAG_MAC flag
E1000_FLAG_MAC was only used by the hw_compat_2_4[] array,
via the 'extra_mac_registers=off' property. We removed all
machines using that array, lets remove all the code around
E1000_FLAG_MAC, including the MAC_ACCESS_FLAG_NEEDED enum,
similarly to commit fa4ec9ffda7 ("e1000: remove old
compatibility code").
