iio: pressure: bmp280: Add data ready trigger support
The BMP3xx and BMP5xx sensors have an interrupt pin which can be used as
a trigger for when there are data ready in the sensor for pick up.
This use case is used along with NORMAL_MODE in the sensor, which allows
the sensor to do consecutive measurements depending on the ODR rate value.
The trigger pin can be configured to be open-drain or push-pull and either
rising or falling edge.
No support is added yet for interrupts for FIFO, WATERMARK and out of range
values.
