A handful of Xe_LPG workarounds are also relevant to graphics version
12.74 as well. Extend the graphics version range for these workarounds
accordingly.

Since the PCI IDs for PVC weren't added to the xe driver, the xe_wa
tests should not try to create a fake PVC device since they can't find
the right PCI ID. Fix bugs when running kunit:

Creating one module for each compilation unit to be tested seems
excessive as the number of tests increase. Group them all in a single
kunit test module called xe_test.ko.
The tests requiring the physical device, aka "live" tests, are still
kept in separate modules since they are normally triggered via igt,
and not via kunit.py. After igt is converted, those can be merged in
a single module as well.

As workarounds for pre-production DG2 were dropped in
commit 707d1b992cfe ("drm/xe/dg2: Drop pre-production workarounds"),
there's no point running the kunit tests for them. Drop
those steppings from kunit.

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.

In order to avoid mistakes when populating the workarounds, it's good to
be able to test if the entries added are all compatible for a certain
platform. The platform itself is not needed as long as we create fake
devices with enough configuration for the RTP helpers to process the
tables. Common mistakes that can be avoided:
- Entries clashing the bitfields being updated
- Register type being mixed (MCR vs regular / masked vs regular)
- Unexpected errors while adding the reg_sr entry
To test, inject a duplicate entry in gt_was, but with platform == tigerlake
rather than the currenct graphics version check:
{ XE_RTP_NAME("14011059788"),
XE_RTP_RULES(PLATFORM(TIGERLAKE)),
XE_RTP_ACTIONS(SET(GEN10_DFR_RATIO_EN_AND_CHICKEN, DFR_DISABLE))
},
This produces the following result:
