alx: add LICENSE and extend documentation for development process

The LICENSE is ISC and some original code came from me based
on the compat project, I have relicensed that stuff to ISC
and contributed here. The rest is the QCA alx driver which
is all ISC licensed.

The documentation for submitting patches and using the
Signed-off-by is added. This follows the Linux kernel's
Developer's Certificate of Origin 1.1. We don't yet have
a mailing list but what we do have is commitment to support
this by the QCA alx development team. Adrian has offered
to help address the BSD target support.

+Contributions to compat follow the same mechanisms as used in the Linux kernel,

+# Submitting patches
+
+compat and compat-drivers contributions follow the contribution model
+implemented by the Linux kernel. Patches or pull requests for compat and
+compat-drivers must have be signed-offed. If you don't sign off on them they

+email" at the end of each commit, indicating that you wrote the code and have
+the right to pass it on as an open source patch. For exact definition of what
+the Signed-off-by tag is you can read the definition of the "Developer's
+Certificate of Origin 1.1", which you can read here:
