drivers: w1: updates to reflect analog maxim acquisition

Links and the manufacturer name are updated from maxim to analog
for the 1-wire subsystem and the related ds18b20 sensor.

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.
