Simon Glass 6d04819930 Add time_since32() to return microseconds since a start time ...

It is useful to implement timeouts like this:

start = get_time();
while (time_since32(start) < 1000)
   ...

Add a function to make this easy. Note that for efficiency we only
support a 32-bit return value which limits the timeouts to about an
hour.
