[PATCH] unbreak xhci-trace compilation

When commit 84a99f6fc5d4 (xhci: add traces for debug messages in
xhci_address_device) was backported to the owl tree as part of commit
5b2ea66f15396 (usb: add owl usb driver), the specific CFLAGS needed for
xhci-trace.c were missed, causing build breakage:

  CC      drivers/usb/host/xhci-trace.o
In file included from drivers/usb/host/xhci-trace.h:151:0,
                 from drivers/usb/host/xhci-trace.c:15:
include/trace/define_trace.h:79:43: fatal error: ./xhci-trace.h: No such file or directory
