kernel: qca-ssdk: backport support for building as kernel module Currently, SSDK is rather special in the sense that its not being built as a proper out of tree module at all but rather like a userspace application and that involves a lot of make magic which unfortunately broke with make version 4.4 and newer. Luckily QCA finally added a way to build SSDK as an out of tree module and it uses the kernel buildsystem which makes it compile with make 4.4 as well. So lets backport the support for it and switch to using it. Signed-off-by: Robert Marko <robimarko@gmail.com> (cherry picked from commit 957f1ee85eb243c5c7397b1e3842a3c61a6b852f)
