i2c:nv_hawk_owl: Reduced sensor stream on time.

Browse Source 
Following changes are done to reduce 400ms to 200ms:
1> I2c address trans during every power_on is moved to probe time.
   Since with virtual-i2c mux IMUs are handled and hence we don't need to
   do i2c address trans every time. So once during probe time is enough,
   that reduces ~120ms.
2> Reduced sleeping time during start stream call to 20ms, Which reduced
   ~100ms.
