drivers: w1: updates to reflect acquistion of maxim by analog devices

[str4t0m]

After the acquisition of Maxim Integrated the documentation of these devices has been moved to the analog.com website. Redirects exist, so they are not broken yet, but we should not rely on that forever.
Therefore the links in the drivers and the sensor sample are updated.

Thanks!

Nit: you may want to split URL updates and other Maxim->Analog renames in different commits, or just reword the single commit message so that it's better aligned with the nature of the update (see e.g. some C files where there's no URL being updated, contrary to what the commit message says)

Thanks for this!

I started to just update the links, then noticed a few additional things.

I've decided to just update the commit message and additionally split off the changes in the sample into a separate commit. I hope the description is now better reflecting the changes done.
