Chris Wilson 6bada3e2d4 igt/gem_softpin: Remove false dependencies on esoteric features
For softpinning, we do not require either userptr or extended ppgtt, so
remove those requirements and make the tests work universally. (Certain
ABI tests require large GTT, or per-process GTT.)

In the process, make the tests more extensive - validate overlapping
handling more careful, explicitly test no-relocation support, validate
more ABI handling. And for fun, cause a kernel GPF.
