ipa: Move kernel-tests from ip_accelerator to techpack.
Move ip_accelerator which is a part of kernel-tests-internal from kernel to techpack. Updated up to SHA1: b8790774643dbfea5b312ed422ef86b54e4c8d7f The kernel-test-module was moved into the driver, and will be compiled as part of debug build. Change-Id: I427b9ea061401c74845d2bd0d505da747d5fe89f Acked-by: Eliad Ben Yishay <ebenyish@qti.qualcomm.com> Signed-off-by: Amir Levy <alevy@codeaurora.org> Signed-off-by: Ilia Lin <ilialin@codeaurora.org>
