fmd,dpaa_eth: Selectively reenable FMan allocation algorithm
On P3/P4/P5 platforms, as well as on P1023, FMan's default resource
allocation values are not enough to enable jumbo frame forwarding in the
absence of SG support. Enable the (previously deselected) FMan dynamic
resource allocation algorithm on those platforms, if the legacy
DPAA-Ethernet driver (missing SG support) is used.
