336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

a5d32c37d9 net: mdio-uclass: rename arguments of dm_mdio_phy_connect for clarity
Renamed dm_mdio_phy_connect arguments dev to mdiodev and addr to phyaddr
for a bit more clarity and consistency with the following patches.
Also use NULL instead of 0 on error return path.

6b3abc0482 net: mdio-uclass: name MDIO according to device-name property if preset
Use the optional property device-name to name the MDIO bus.  This works
around limitations with using the DT node name on devices such as
Armada-8040, which integrates two cp100 cores, both featuring MDIOs at the
same relative offsets and with the same DT node names.
The concept was originally proposed by Marvell as a custom property called
mdio-name specific to Marvell driver.  This patch uses the more generic
property device-name and moves this into MDIO class code so other can use
it as well.

c3452b50c3 net: introduce MDIO DM class for MDIO devices
Adds UCLASS_MDIO DM class supporting MDIO buses that are probed as
stand-alone devices.  Useful in particular for systems that support
DM_ETH and have a stand-alone MDIO hardware block shared by multiple
Ethernet interfaces.
