Merge ~canonical-kernel-team/+git/autotest-client-tests:portias/xilinx into ~canonical-kernel-team/+git/autotest-client-tests:master

[Portia Stephens]

This adds regression tests for the linux-xilinx-zynqmp/focal kernel. These tests are expected to run on Xilinx hardware, specifically kv260 and zcu boards. These scripts were copied and modified from the raspberry_pi regression tests. v1 and v2 of these scripts were send via email.

[Po-Hsu Lin (cypressyew)]

LGTM.
Tested on ZCU102 and it works.
+1 here.

review: Approve

[Po-Hsu Lin (cypressyew)]

Applied and pushed.
Let's get this rolling!

I will update the test plan in CKCT later.

[Francis Ginther (fginther)]

@cypressyew Thanks for reviewing and applying. I have no additional comments. LGTM.
