drivers: sensor: sdp3x: add driver

[ygaillard]

This is a proposition for a driver using the SDP3x family differential pressure sensors. The related documentation can be found via https://sensirion.com/media/documents/4D045D69/6375F34F/DP_DS_SDP3x_digital_D1.pdf. The code was tested using a SDP31 chip on custom hardware in ambient conditions and return plausible data.

Trigger and continous mode can be selected via project file. The board file select the different mesure mode provided by the sensor.

@carlescufi , finally fixed my issues.

Thanks for the contribution!

Please add this sensor to tests/drivers/build_all/sensor

Use i2c_is_ready_dt

[ygaillard]

This seems to cause an invalid pointer. Could you provide more information on how to use this function? Note that the other implemented sensirion drivers use device_is_ready.

Log:

In function 'sdp3x_init':

Thanks for the contribution!

Please add this sensor to tests/drivers/build_all/sensor

Can you please point in the coding guidelines how to implement the test? I could not find any for the other sensirion sensors and therefore difficult how to implement them.

[ygaillard]

I implemented the changes. Did I miss something in the workflow?

rebased to re-trigger stuck CI

[ubieda]

Thanks for your contribution! Code looks good but needs the indentation fixed and address Maureen's comment.

Please fix indentation (various places): spaces -> tabs
