soc/qualcomm/common: Make clock_configure() check for exact matches

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
not 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.

BUG=b:198627043
BRANCH=None
TEST=build herobrine image and try to set SPI frequency to number not
     supported.  Ensure device doesn't boot.
