GIC tests seems to rely on MSI-X feature being enabled for v3 + ITS

[camwilde77]

From my understanding, the GIC (GIV v3 + ITS) tests can be set up as MSI or MSI-X. v3 + ITS can have full MSI-X support at the RP, but doesn't have to use it. You could also have an endpoint that supports it (or not). As far as I can tell, the BSA code expects that MSI-X is always supported for GIC v3 + ITS, but a system could still decide to not do that. Shouldn't these tests default to MSI when the RP compatibility register shows MSI-X as not enabled? This seems to affect tests 904, 911. 912, and 913.

I agree with the comment here. BSA PCIe exerciser tests should check both MSI and MSI-X capable endpoint devices rather than only MSI-X capable endpoint devices.

@gowthamsiddarthd and @chetan-rathore Can we get ACS team to fix the issue?
