hwmon: (tmp401) Add OF device ID table

This driver doesn't have of_match_table. This makes the kernel module
tmp401.ko lack alias patterns (e.g: of:N*T*Cti,tmp411) to match DT node
of the supported devices hence this kernel module will not be
automatically loaded.

After adding of_match_table to this driver, the folllowing alias will be
added into tmp401.ko.
$ modinfo drivers/hwmon/tmp401.ko
filename: drivers/hwmon/tmp401.ko
