Change this to "amstaos,as3935"

amstaos (AMS bought Taos) is already a registered vendor prefix in
vendor-prefixes.txt

When using generic binding properties, please reference the binding
being used. Like:

	- spi-cpha: SPI Mode 1. Refer to spi/spi-bus.txt for generic SPI
	  slave node bindings.

	Refer to interrupt-controller/interrupts.txt for generic
	interrupt client node bindings.

What is this? Why not just ams,tune-cap = <10>; ?

It's a value between 0-15, right?
