ds18b20: fix delay timing error in ds18b20_update()

Browse Source 
Due to the change of using upm_delay_ms() instead of usleep(), but
failing to adjust the delay time accordingly, ds18b20_update() was
waiting for 750000ms (12 minutes) before reading the result of a
measurement, instead of the more appropriate 750ms.

This should fix Issue #530.
