Hi Al,

Some BRCMSTB USB chips have an XHCI, EHCI and OHCI controller
on the same port where XHCI handles 3.0 devices, EHCI handles 2.0
devices and OHCI handles <2.0 devices. Currently the Makefile
has XHCI linking at the bottom which will result in the XHIC driver
initalizing after the EHCI and OHCI drivers and any installed 3.0
device will be seen as a 2.0 device. Moving the XHCI linking
above the EHCI and OHCI linking fixes the issue.

I tested on my environment (r8a77951 and r8a77961) and then
I didn't detect any regression. So,
