Add a new subtest that performs suspend-to-mem and -disk, but instead of
doing the full sequence it suspends/resumes only devices. A failed S3/4
subtest and a successful S3/4-devices subtest would indicate a kernel core
or BIOS problem as opposed to some issue in the driver.
v2:
- Add a new basic-S3-devices subtest too. (Chris)

To have a more accurate idea about any suspend/resume issues we can
perform the s/r until various phases in the s/r sequence. This way we
can isolate the given problem as being a device driver, kernel core or
BIOS related issue. Actual subtests using these new s/r phases will be
added as follow-up.
While at it also add the freeze suspend target, it's something we also
would need to test.

It access hardware, hence why the simple igt_only_list_subtests()
check from igt_fork/stop_signal_helper() isn't enough.

The selftest is already before the suspend/hibernate tests, but to be
clear also run it first (it only takes a millisecond) by itself.

Add a couple of all-engine busy tests in order to exercise coherency and
general bugs across suspend. (In particular, I expect this to trigger a
fresh case of lockdeps on Braswell, as well as the usual battery of
missing rpm references. This is an exerciser for my lockless-suspend
patches.)

Filter out the request to execute on gen6/bsd to prevent skips.

Keep an eye on domain tracking for both cached/uncached objects across
suspend.

Check that the system operates normally before and after the suspend (as
well as across the suspend). The goal is to isolate the breakage to the
subtest.
