The '_d' suffix was originally introduced in case we want to import
Linux struct device as a separate struct into barebox. Over time it
became clear that this won't happen, instead barebox struct device_d
is basically the same as Linux struct device. Rename the struct name
accordingly to make porting Linux code easier.

The Designware MAC on the StarFive jh7100 needs some special speed
configuration. Match against a new starfive,stmmac compatible that
describes that.

drivers/net/designware.c handles the older Designware < 4.x MAC IPs,
which do not support DMA beyond 32-bit. They are still being integrated
into SoCs with 64-bit CPUs like the StarFive JH7100, which additionally
needs a non 1:1 mapping for coherent DMA.
Fix the driver to support such usage. The driver still has the assumption
that barebox core will only pass it 32-bit pointers. This is now made
explicit by returning error codes when the DMA mask is violated.

Barebox-version of the Linux v5.2 patch:
40ae25505fe834648ce4aa70b073ee934942bfdb
net: stmmac: socfpga: fix phy and ptp_ref setup for Arria10/Stratix10
On the Arria10, Agilex, and Stratix10 SoC, there are a few differences from
the Cyclone5 and Arria5:
- The emac PHY setup bits are in separate registers.
- The PTP reference clock select mask is different.
- The register to enable the emac signal from FPGA is different.
Thus, this patch creates a separate function for setting the phy modes on
Arria10/Agilex/Stratix10. The separation is based a new DTS binding:
"altr,socfpga-stmmac-a10-s10".

The new DTS binding is already part of v2019.10.0 and the driver doesn't
probe on Arria10 without the new binding introduced in this patch.

Halt is not automatically executed if we start the kernel.
So, we may have potentially memory corruptions.

As the eth_device and mii_bus structs are allocated inside the
dw_eth_dev struct a forward declaration isn't enough.

The designware ethernet core is used on multiple different SoCs.
The linux kernel has a generic driver and SoC-specific drivers.
Do the same here.

The FSF address has changed; The FSF site says that
address is
Free Software Foundation
51 Franklin Street, Fifth Floor
Boston, MA 02110-1301
USA
(see http://www.fsf.org/about/contact/)
Instead of updating it each time the address changes,
just drop it completely treewide.

Instead of hardcoding the alternate/enhanced descriptor layout make
it configurable during runtime. This is based on the value of the
enh_desc variable which is currently hardcoded to zero. This should
be configurable via device_id in the future. Since currently we have
no in tree user of this driver this currently doesn't hurt.
