The newly added phy-dm816x-usb driver depends on the
usb phy API and fails to link if that is disabled:

drivers/built-in.o: In function `dm816x_usb_phy_remove':
:(.text+0x3a28): undefined reference to `usb_remove_phy'
drivers/built-in.o: In function `dm816x_usb_phy_probe':
:(.text+0x3c18): undefined reference to `usb_add_phy_dev'

This adds an explicit dependency in Kconfig to avoid the
build error in randconfig tests.
