[PATCH 1/3] rockchip: Fix TPL link error

[FUKAUMI Naoki]

Rockchip RK3399 targets build TPL. If CONFIG_SPL_USB_DWC3_GENERIC and
CONFIG_SPL_USB_GADGET are enabled, linking u-boot-tpl will fail.

  LD      tpl/u-boot-tpl
ld.bfd: drivers/usb/dwc3/dwc3-generic.o: in function `dwc3_glue_bind_common':
/home/radxa/u-boot/drivers/usb/dwc3/dwc3-generic.c:527:(.text.dwc3_glue_bind_common+0x20): undefined reference to `usb_get_dr_mode'

Do not compile drivers/usb/ for TPL.
