Julius Werner c575a5c958 libpayload: ehci: Set explicit terminate bits in dummy_qh next pointers. 
The EHCI host controllers in Samsung Exynos SoC seem to be a little more
picky than Intel ones. When they reach the dummy_qh in the periodic
frame list, they try to access the next qTD pointer even though it's
NULL, an run into a HostSystemError. This patch explicitly sets the
Terminate bit on those pointers to mark them invalid.

BUG=chrome-os-partner:18635
TEST=Fix all the other issues with EHCI on ARM, then make sure it works.
