[PATCH 1/6] drivers/Makefile: Fix TPL build with dwc3 generic

[Arnaud Patard]

When building TPL with DWC3 generic enabled, the following error is
occuring:
aarch64-linux-gnu-ld.bfd: drivers/usb/dwc3/dwc3-generic.o: in function `dwc3_glue_bind_common':
.../drivers/usb/dwc3/dwc3-generic.c:527: undefined reference to `usb_get_dr_mode'
