Jim Lin 627de92d0a libpayload ehci: Use 64-byte aligned data structures for periodic transfers
Chapter 3.1 "Periodic Frame List" of EHCI 1.0 specification says
"Frame List Link pointers always reference memory objects that are
32-byte aligned."
jwerner@chromium.org suggests setting it to be 64-byte aligned for
consistency with other EHCI queue structures.

BUG=chrome-os-partner:31993
TEST=Tested on nyan platform. Before adding patch, USB keyboard behind
an external hub is not working to switch between "Default Locale" and
"English" (after pressing ESC+REFRESH+POWER on embedded keyboard and
later Left/Right-Arrow key on USB keyboard).
