build: d1: add SUPPORTED_DEVICES

Include specific SUPPORTED_DEVICES values derived from the .dts file.
This makes the generated profiles.json consistent with the 'board_name' from
'ubus call system board'.

Specifically, this fixes a bug in the generated profiles.json that breaks the
ASU clients when selecting the proper image from a build.

See the 'supported_devices' fields here for the incorrect (or incomplete) list:
