dt/i2c: Enumerate some of the known trivial i2c devices

Based on recent discussions, we apparently want to do bindings even for
trivial i2c devices, even though they have for years just been added. So
start a table of the currently known ones for others to be added to
over time.

(I am intentionally letting lines go over 80 characters to make it easier
to sort the file).

+This is a list of trivial i2c devices that have simple device tree
+bindings, consisting only of a compatible field, an address and
+possibly an interrupt line.
+
+If a device needs more specific bindings, such as properties to
+describe some aspect of it, there needs to be a specific binding
+document for it just like any other devices.
