phy: bcm-ns-usb3: fix MDIO_BUS dependency

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.
