usb: phy: add USB_SUPPORT dependency
The driver now calls of_usb_get_dr_mode_by_phy, which is part of the
USB core layer, and it fails to build when that is not provided:
drivers/phy/phy-sun4i-usb.o: In function `sun4i_usb_phy_probe':
phy-sun4i-usb.c:(.text.sun4i_usb_phy_probe+0x140): undefined reference to `of_usb_get_dr_mode_by_phy'
We already have a couple of other PHY drivers with a dependency
on USB_SUPPORT, so that seems to be the easiest fix here.
An alternative would be to adjust the #ifdef in include/linux/usb/of.h
to also check for CONFIG_USB_SUPPORT.
