2FOC test procedure needs to be updated

[MSECode]

Since there are some of the instruction of the 2FOC test procedure that are outdated we need to update them. This won't block the test but some of the instructions can be misleading to any tester so we need to clarify them well.

I've opened a PR here: https://github.com/icub-tech-iit/electronics-legacy/pull/80

where we have updated the xml files which contains the steps of the test sequence. Basically now we have integrated the instruction of a couple of tests, so that are cleaner to be read and understood.
Moreover, we have added the flashing of bl and fw on the second phase of the sequence, in a way that when we are doing the test with a goldenboard we are sure that the fw on the 2FOC is actually the test fw.

@MSECode about the PR is there any overlap or duplicate file to manage in the non-legay repo? im referring to https://github.com/icub-tech-iit/electronics-boards/tree/master/2foc/sw

Actually yes, but it is just for giving more details to the tester. Basically, when I show in the test procedure how to check which version of the 2foc you are using, I've also add a link to the logic. Therefore, if needed, one can check exactly if the used version of the 2foc is mounting or not the CAN-H/CAN-L resistors. So yes, we should pay attention to changing in the folders of electronics-boards if they might happen in the future.

Updates needed are ready. In order to move the related PR to ready I'll wait for the test equipment to arrive from the supplier to test if the modifications done are fine.
