Add support for setting and retrieving OverSampling Rate independently for
each of the temperature and pressure channels. This allows userspace to
fine tune hardware sampling process according to the following tradeoffs :
* the higher the OSR, the finer the resolution ;
* the higher the OSR, the lower the noise ;
BUT:
* the higher the OSR, the larger the drift ;
* the higher the OSR, the longer the response time, i.e. less samples per
unit of time.

Previously most drivers that used a i2c_check_functionality() check
condition required various error codes on failure. This patchset
converts to a standard of -EOPNOTSUPP

This will be used together with an external trigger (e.g hrtimer
based software trigger).

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

MS5607 is temperature and pressure sensor which hardware is similar to MS5611.
Both sensors share command protocol and support both I2C and SPI serial
protocols. They only differ in compensation algorithms.
