Rework SPL06 to do background updates compliant with the spec

[andyp1per]

Pulls in some bug fixes from betaflight to make the code more understandable.
Enabled background updates by default (which is what the DPS310 driver does)
Uses external temperature sensor as required by the spec.

This results in much more accurate baro updates from this sensor.

Tested on BetaFPV F405

@radiolinkW this PR will directly affect your board RadiolinkPIX6

Wu was the committer on the commit which added to the SPL06 driver to add SPA06 support, and to add the ability to do "background" reading on this sensor.

@andyp1per has tested this on a board he is currently working on, and the background reading does improve the driver's performance significantly.

Would it be possible for you to test this PR on your RadiolinkPIX6 board and verify that the Baro still works as expected?

Regarding TMP_EXT(external temperature sensor), it is in the TMP_CFG register of SPL06, but in the MEAS_CFG register of SPA06.

[peterbarker]

Looks like this would have us write incorrect configuration into the SPA06.

Thanks for checking, we'll make sure we don't break that bit.

Can you confirm https://vi.aliexpress.com/item/1005007607117391.html?gatewayAdapt=glo2vnm always contain the SPA06, please? It'll be worth getting one of those into an ArduPilot DevTeam member's hands so we can check we're not breaking this sensor without bugging you :-)

[andyp1per]

Fixed

@andyp1per I think you should buy one of these boards so we can test the driver changes, can you apply for funding for that?

BETAFPV-F405 doesn't list the SPL06 baro in hwdef? is this a variant?

Yes, the RadiolinkPIX6 we ship includes the SPA06 baro, and we are waiting for you to release the 4.6 firmware because only the 4.6 firmware supports the SPA06 driver.
When will you release the 4.6 firmare?

We can provide a free RadiolinkPIX6 for you to test the SPA06 driver.
@andyp1per Can you provide me with your email address so that i can send you a free RadiolinkPIX6 purchase link?

@tridge TBH the other option is to delete the driver and fold the SPA06 fixes into the DPS310 driver - BF only has one driver

So both SPL06 and SPA06 would move to the DPS310? Interesting...

We're just about to release -beta3 for 4.6 Can't be that much longer!

@radiolinkW are you able to test this change on your board? I sent you e-mail, but response so far.

I haved replied to your email. We are on Spring Festival holiday and probably cannot test it.

Tested on SpeedyBeeF405AIO which has an SPA6 - checked out. I added the correct devid so that we can identify the different parts.

The temperature register that @radiolinkW were interested in is functional?

Right, that fix is part of this PR
