The driver attempts to 'select MDIO_DEVICE', but the code
is actually a loadable module when PHYLIB=m:
drivers/phy/broadcom/phy-bcm-ns-usb3.o: In function `bcm_ns_usb3_mdiodev_phy_write':
phy-bcm-ns-usb3.c:(.text.bcm_ns_usb3_mdiodev_phy_write+0x28): undefined reference to `mdiobus_write'
drivers/phy/broadcom/phy-bcm-ns-usb3.o: In function `bcm_ns_usb3_module_exit':
phy-bcm-ns-usb3.c:(.exit.text+0x18): undefined reference to `mdio_driver_unregister'
drivers/phy/broadcom/phy-bcm-ns-usb3.o: In function `bcm_ns_usb3_module_init':
phy-bcm-ns-usb3.c:(.init.text+0x18): undefined reference to `mdio_driver_register'
phy-bcm-ns-usb3.c:(.init.text+0x38): undefined reference to `mdio_driver_unregister'
Using 'depends on MDIO_BUS' instead will avoid the link error.

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".

This is driver for USB DRD PHY used in Broadcom's Northstar2
SoC. The phy can be configured to be in Device mode or Host
mode based on the type of cable connected to the port. The
driver registers to extcon framework to get appropriate
connect events for Host/Device cables connect/disconnect
states based on VBUS and ID interrupts.

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.
