Merge ~djacobs98/checkbox-provider-iiotg:djacobs98_qep into checkbox-provider-iiotg:main

[Doug Jacobs]

Initial check-in for automated tests for Quadrature Encoding Peripheral.

Added single test case to detect QEP devices on PCI bus.
(QEP is only supported on IOTG EHL platforms. The test fails as expected on my IOTG TGL board.)

Thanks!

Just a quick request below.

Added test plans for Full, Manual and Automated so QEP is consistent with other test plans.

I spotted a typo in your test (see below).

I'm having trouble testing this on my device, because Checkbox somehow does not recognize the `has_qep` manifest. I'll look into that.

Another issue is that, as expected, these ids (4bc3, 4b81, 4b82, 4b83) don't return anything on my Aaeon EHL board, which means this job is too specific to be useful. We'll need to discuss with Cert on how to go from there. Either have something like what's been done for the GPIO pins (a file per device hosting the proper IDs to be checked), either something else...

If I understand the intention then I don't believe this will work. Checkbox will evaluate the result based only the last statement only, so in the case the line including 4b83. I think some more logic is needed to establish if the detect should pass based on a AND or OR of the searches.

Added test-plan.pxu. Verify tests can run (fails on my hardware as expected.)

Added additional test commands to check if QEP is enabled the devices show up in lspci
