af850e14a7 phy: bcm-ns-usb3: add MDIO driver using proper bus layer 
As USB 3.0 PHY is attached to the MDIO bus this module should provide a
MDIO driver and use a proper bus layer. This is a proper (cleaner)
solution which doesn't require code to know this specific MDIO bus
details. It also allows reusing the driver with other MDIO buses.

For now keep platform device support in place. We may consider dropping
it once MDIO bindings gets used "everywhere".

4536adee0a phy: bcm-ns-usb3: enable MDIO in the platform specific code 
When we finally start using MDIO layer then bus initialization will be
handled in a separated driver. It means our code handling this has to be
used for the platform driver only.

b20f506f6c phy: bcm-ns-usb3: use pointer for PHY writing function 
Our current writing function accesses PHY directly bypassing MDIO layer.

The aim is to extend this module to also behave as MDIO driver. This
will require using different writing function which can be handled
cleanly by having an extra pointer like this.

412512c4f9 phy: bcm-ns-usb3: always wait for idle after writing to the PHY reg 
Move MDIO specific code to the writing helper function. This makes init
code a bit more generic and doesn't require it to track what happens
after every write.

0b56e9a7e8 phy: Group vendor specific phy drivers 
Adding vendor specific directories in phy to group
phy drivers under their respective vendor umbrella.

Also updated the MAINTAINERS file to reflect the correct
directory structure for phy drivers.
