Subject: [PATCH 05/11] iio: pressure-core: st: Describe LPS331AP defines by name

Hi Lee,

You are right, but the reason is to maintain the same structure of the 
other sensors drivers (like accel, gyro and magn). Often some sensors 
can use the same data and using 1,2,... I think it's more general.
