Declaration of of_usb_get_dr_mode_by_phy only depends on CONFIG_OF
and not on CONFIG_USB_SUPPORT, which actually defines it. This can
break the build like below, if USB_SUPPORT is not selected :

 drivers/phy/renesas/phy-rcar-gen3-usb2.o: In function `rcar_gen3_phy_usb2_probe':
 drivers/phy/renesas/phy-rcar-gen3-usb2.c:444: undefined reference to `of_usb_get_dr_mode_by_phy'
 drivers/phy/renesas/phy-rcar-gen3-usb2.c:444:(.text+0x2d4): relocation
  truncated to fit: R_AARCH64_CALL26 against undefined symbol `of_usb_get_dr_mode_by_phy'
 drivers/phy/renesas/phy-rcar-gen3-usb2.c:444: undefined reference to `of_usb_get_dr_mode_by_phy'
 drivers/phy/renesas/phy-rcar-gen3-usb2.c:444:(.text+0x3bc): relocation truncated to
  fit: R_AARCH64_CALL26 against undefined symbol `of_usb_get_dr_mode_by_phy'
 make: *** [Makefile:993: vmlinux] Error 1

Fixes: commit 98bfb39466954c69d2 ("usb: of: add an api to get dr_mode by the phy node")
