Subject: [PATCH -next] net/phy: fix phy_bcm_nsp_usb3.c build and kconfig

From: Randy Dunlap <rdunlap@...radead.org>

This driver uses mdio* (PHYLIB) interfaces, so it should select
PHYLIB. PHYLIB depends on NETDEVICES to this driver should also
depend on NETDEVICES.

Fixes these build errors:

drivers/built-in.o: In function `nsp_usb3_phy_init':
phy-bcm-nsp-usb3.c:(.text+0x42d8): undefined reference to `mdiobus_write'
phy-bcm-nsp-usb3.c:(.text+0x42f4): undefined reference to `mdiobus_write'
