selftests/powerpc: Remove Power9 copy_unaligned test This is a test of the ISA 3.0 "copy" instruction. That instruction has an L field, which if set to 1 specifies that "the instruction identifies the beginning of a move group" (pp 858). That's also referred to as "copy first" vs "copy". In ISA 3.0B the copy instruction does not have an L field, and the corresponding bit in the instruction must be set to 1. This test is generating a "copy" instruction, not a "copy first", and so on Power9 (which implements 3.0B), this results in an illegal instruction. So just drop the test entirely. We still have copy_first_unaligned to test the "copy first" behaviour.

selftests: remove duplicated all and clean target Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt.
