Describe problem solved by this pull request
Added the driver of spl06 barometer. as the issue #13547

Describe your solution
it's a simple driver, just like how BMP280 implement.

Describe possible alternatives
A clear and concise description of alternative solutions or features you've considered.

Test data / coverage
I tested it on linux(SPI/I2C), while there may be problems on nuttx.

Additional context
if someone could test it on nuttx, it would be very nice. Because of this, I commented the spl06 dir in CMakeFiles, just for someone who really need this driver.

Is this the Goertek SPL06-007? https://datasheet.lcsc.com/szlcsc/1907081118_Goertek-SPL06-007_C233787.pdf

Could you move it under src/drivers/barometer/goertek/spl06? That's how I'm slowly reorganizing the drivers (eg drivers/imu).

hi, @dagar do you have time to review this patch? Is there any other problems in the patch?
I'm afraid that you forgot this issue.
If you are busy doing some other work, please ignore the notice.

The change looks good. Do you intend to use this in a custom board or as an external peripheral on existing boards? If external might want to add a parameter like this to autostart.

PX4-Autopilot/ROMFS/px4fmu_common/init.d/rc.sensors

Lines 146 to 150 in c2c455b

	# TE MS5525 differential pressure sensor external I2C
	if param compare -s SENS_EN_MS5525 1
	then
	ms5525_airspeed start -X
	fi

[Ncerzzk]

I added it behind the condition: SENS_EXT_I2C_PRB, is it OK?

No, that doesn't scale well and there are potential conflicts that develop over time. It's better to do it explicitly now.

All you need to do is add a parameter, and then the little bit of code in rc.sensors.

Lines 34 to 41 in c2c455b

	/**
	* TE MS5525 differential pressure sensor (external I2C)
	*
	* @reboot_required true
	* @group Sensors
	* @boolean
	*/
	PARAM_DEFINE_INT32(SENS_EN_MS5525, 0);

OK, done.

removed -q option when starting spl06.
