[Asa-dev] [CI] SBSA ACS tests

I added new CI job: ldcg-sbsa-acs.

It builds HEAD of qemu and edk2 and then use it to run Arm SBSA ACS testsuite for SBSA levels 3-6.

https://snapshots.linaro.org/ldcg/sbsa-acs/3/ has logs from each run.

This allows us to check which components are still missing for each level.

I created some Jira cards yesterday to list missing parts:

ASA-65 - add PMU counters ASA-66 - add GIC ITS support ASA-67 - add Virtual Host Extensions (required for level 4) ASA-68 - add SMMU (it is not detected by SBSA ACS now)

I plan to look at those logs and create additional cards so we can see what is still missing (or not enabled).

Next run will have larger timeout as 30s looks a bit too short.
