hwmon: (lm90) Mark alert as broken for MAX6646/6647/6649

BugLink: https://bugs.launchpad.net/bugs/1959879
commit f614629f9c1080dcc844a8430e3fb4c37ebbf05d upstream.

Experiments with MAX6646 and MAX6648 show that the alert function of those
chips is broken, similar to other chips supported by the lm90 driver.
Mark it accordingly.
