mvebu: enable Aquantia phy driver for Puzzle devices

While on Linux 5.10 this fixes Ethernet link status on all ports and
makes 2.5G ports usable in 2.5G and 1G full-duplex mode, when using
Linux 5.4 and backported Aquantia phy patches, only 1G mode works on
the 2.5G ports and link speed and duplex are not reported correctly
from the phy in case of 2.5G.
The reasons are probably trivial, but hard to find. As having all
ports work at least in 1G speed instead of having them not work at
all is still better, push this anyway for now.
