Add a simple kunit test to ensure each platform's GT per tile count is
non-zero and does not exceed the global XE_MAX_GT_PER_TILE definition.
We need to move 'struct xe_subplatform_desc' from the .c file to the
types header to ensure it is accessible from the kunit test.
v2:
- Rebase on latest xe_pci test rework from Michal and convert to
a parameterized test that runs on each PCI ID supported by the
driver.

We missed to drop it in commit 50680d1698 ("drm/xe/tests: remove
unused leftover xe_call_for_each_device()") so drop it now.

Instead of iterating over available Xe devices within a testcase,
without being able to distinguish potential failures from different
devices on system with many Xe devices, introduce helpers that will
allow to treat each Xe device as a parameter for the testcase like:
static void bar(struct kunit *test)
{
struct xe_device *xe = test->priv;
...
}
struct kunit_case foo_live_tests[] = {
KUNIT_CASE_PARAM(bar, xe_pci_live_device_gen_param),
{}
};
struct kunit_suite foo_suite = {
.name = "foo_live",
.test_cases = foo_live_tests,
.init = xe_kunit_helper_xe_device_live_test_init,
};

We want to add code that will check the driver's SR-IOV mode.
Update xe_pci_fake_device_init() and struct xe_pci_fake_data to
either explicitly specify desired SR-IOV mode of the fake device
or fallback to the default bare-metal mode.

Currently it's not possible to test the WAs for platforms using gmdid
since they don't have the IP information on the descriptor struct. In
order to allow that, add a stub function for read_gmdid() that is
activated when the test executes, replacing the iomap and read of the
real register.

Instead of passing as parameter to xe_pci_fake_device_init(), use
test->priv to pass parameters down the call stack. The main advantage is
that then the data is readily available on other functions by using
kunit_get_current_test().
This is a preparation to fix the initialization of fake devices when
they were supposed to be using GMD_ID.

Add a simple KUnit test to ensure that the hardware engine lists for
GMD_ID IP definitions are sensible (i.e., no graphics engines defined
for the media IP and vice versa).
Only the IP descriptors for GMD_ID platforms are checked for now.
Presumably the engine lists on older pre-GMD_ID platforms shouldn't be
changing. We can extend the KUnit testing in the future if we decide we
want to check those as well.
v2:
- Add missing 'const' in xe_call_for_each_media_ip to avoid compiler
warning.

Instead of requiring tests to initialize a fake device an keep it in
sync with xe_pci.c when it's platform-dependent, export a function from
xe_pci.c to be used and piggy back on the device info creation. For
simpler tests that don't need any specific platform and just need a fake
xe device to pass around, xe_pci_fake_device_init_any() can be used.

Move code out of xe_pci.[ch] into tests/*.[ch], like is done in other
similar compilation units. Even if this is not part of "tests for
xe_pci.c", they are functions exported and required by other tests. It's
better not to clutter the module headers and sources with them.
