AR2315 Ethernet driver pass NULL instead of a real device pointer to DMA
(un-)map calls. With kernel version 5.4 such behaviour causes a kernel
panic. Fix this issue by preserving device pointer during the probe
procedure and pass it to each skb data DMA (un-)map call.

Rework ethernet supported link modes to linkmode bitmask.
This is needed to suppress compilation errors:
drivers/net/ethernet/atheros/ar231x/ar231x.c:1153:20: ...
error: assignment to expression with array type
phydev->supported &= (SUPPORTED_10baseT_Half

Discussion on the mailing list reveals that this target has active
users. As we are finally able to upgrade this target to kernel 5.4,
add it back to master.
This reverts commit 7d29a55714 ("ath25: drop target") and
immediately moves the relevant files to 5.4, without touching
the content.
