board: port to iotlab M3 of A8

[aabadie]

Here is a port to the iotlab-a8-m3. I tried to factorize the code with iotlab-m3 as the only changes are:

• some sensor to remove (isl29020 and lps331ap)
• use a different SPI interface (2 instead of 1) and some GPIO changed

I put all the common code in a boards/iotlab-common directory and the specific code in boards/iotlab-m3 and boards/iotlab-a8-m3.

@kYc0o can you review and test this on the hardware?
Would be great to have support for this in the release.

[kYc0o]

Yes sure! I'll review it asap.

[aabadie]

branch rebased and conflicts fixed.

[aabadie]

Any comment on this one ?

[kYc0o]

Sorry for the delay, I'll look into this ASAP.

[aabadie]

Rebased and fixed conflicts with master.

[aabadie]

For the record, I updated the initial branch:

• openocd config files were not found by the flash target : the dist directory is duplicated in both directories
• my previous rebase broke the iotlab-m3 code. It should be fixed now.

Tested in the new IoT-Lab Saclay site, working like a charm. Thanks @aabadie ! Can you add a small wiki and reference the tutorial to test this new functionality?

I tested this PR with the upstream master with this PR merged, so if you want you can reference the upstream repo when merged.

ACK and let's Murdock have a last word!

[kYc0o]

and go!

Ah! I just forgot a small (but important) thing... can you add your name to the sources you've modified? @OlegHahm what's the procedure on this case? Should he add it on a new PR?

[OlegHahm]

Would be probably the best, yes.
