Add support for the Libretech cottonwood board family.
These 2 boards are based on the same PCB, with an RPi B form factor.
The "Alta" board uses an a311d while the "Solitude" variant uses an s905d3.

"activity" isn't documented, perhaps heartbeat instead ?

leds subnodes should be named as led(-[0-9a-f]+)

Ditto, but you can simply use "led" since it's the only one.
