Apart from the missing entry, should it not be the case that we pick the
highest frequency <= than the requested frequency, rather than the next
available (potentially higher) frequency?

IOW I'd expect things to be underclocked at 768MHz without this change,
which would mean that clock_set_pll1 is buggy.
