Previously, clock_configure() will configure the clocks to round up to
the next highest frequency bin. This seems non-intuitive. Changing
the logic to find an exact frequency match and will halt booting if no
match is found. Recently fixed a bug in CB:63311, where the clock was
being set incorrectly for emmc and was able to find it because of this
stricter check.
