Describe HWE kernel, point release and url for supported arm64 platform

[dann frazier (dannf)]

Thanks Ike! Sorry for the late review. Comments inline. I'd also ask that we get someone from the kernel team to +1 the MP, since we're describing their product.

-	    expected in the future. Most of the hardware is supported
