Subject: [PATCH] phy: rcar-gen3-usb2: add dependency on USB

Following error showed up:

drivers/phy/renesas/phy-rcar-gen3-usb2.o: In function `rcar_gen3_phy_usb2_probe':
/work/tools/linux/drivers/phy/renesas/phy-rcar-gen3-usb2.c:444: undefined reference to `of_usb_get_dr_mode_by_phy'
Makefile:993: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

with CONFIG_USB_SUPPORT=n

Add dependency on USB_SUPPORT and select USB_COMMON to make sure that
of_usb_get_dr_mode_by_phy() is available.
