net: dsa: b53: Fix build with B53_SRAB enabled and not B53_SERDES
In case B53_SRAB is enabled, but not B53_SERDES, we can get the
following linking error:
ERROR: "b53_serdes_init" [drivers/net/dsa/b53/b53_srab.ko] undefined!
We also need to ifdef the body of b53_srab_serdes_map_lane() since it
would not be used when B53_SERDES is disabled and that would produce a
warning.
