ish5: fast 32-bit division in scale_us2ticks
The critical section using scale_us2ticks is in __hw_clock_source_set,
which we can optimize as this has 32-bit inupts and outputs.
Make a separate function for this usage, scale_us2ticks_32, to be used
in this critical section.
BUG=b:133190570
BRANCH=none
TEST=tested outputs of scale_us2ticks_32 to make sure they matched the
correct value for 32-bit inputs
