Subject: [PATCH] overlays: Add missing addresses to ads1015/ads1115
The overlays for the ads1015 and ads1115 I2C ADCs omitted the addresses
in the main device node names. As well as breaking the conventions for
I2C devices, this prevents the firmware from renaming them when the
"reg" property is modified, which in turn stops the overlays from being
instantiated multiple times.
