This introduces a dummy queue head in the interrupt frame list of the
EHCI host controller. It's a workaround for broken controllers which
follow pointers from this list even if the terminate bit is set.
Fortunately, they do honor the bit in queue heads and having an empty
QH in the list doesn't violate the standard.
The linux kernel has a similar workaround for AMD SB700, SB800, and
Hudson-2/3 platforms. We observed this bug with an AMD SB600.

If the queue of an interrupt transfer runs out, we have to reset
the queue head. This also introduces the use of a spare transfer
descriptor (TD) in interrupt queues, which assures, that a processed
TD won't be reused until the host controller has written it back
from his overlay.

The 'name' argument to lookup_cmos_entry() is declared to be 'char *'
but we pass an empty string ("") which is 'const char[]' so the compiler
legitimatly warns about discarded qualifiers here. Fix this by passing
NULL as 'name'.
Minor nitpick: The NULL test in lookup_cmos_entry() is superfluous as our
implementation of strnlen() can handle NULL pointers gracefully. But for
an average C hacker it just doesn't feel right not to do so.
