The first "S" in SBSA stands for "Server".  I don't think it makes sense 
to put an SBSA watchdog device in a non-server SOC.

Frankly, I don't understand why people want to make this driver work on 
hardware that doesn't exist.  The SBSA is intended for 64-bit ARM 
Servers that use ACPI.  Yes, there are a couple of ARM64 servers that 
use device tree, but those are legacy platforms.
