[CHT] suspend-resume fails due to unrelated USB error

Need to filter this out to pass tests.

===========================>>
[ 7702.164446] hub 2-2:1.0: hub_ext_port_status failed (err = -71)
[ 7702.502167] usb 2-2: Failed to suspend device, error -19
<<===========================

sof-kernel-log-check: ignore USB hub issues

Thanks, can you be more specific than "CHT"?

Also: is this a recent kernel regression?

This is a no-name el-cheapo headless device, the only details I have are from the DMI string:
ZOTAC-XXXXXX-XX-CherryTrailFFD
not very useful, it it?

I have no idea if this USB issue is recent or not, there are a series of issues with sof-test that prevented the tests to run until now. This was the last problem I found, now all tests pass.

@RuiqingX can you please fix this issue?

sof-kernel-log-check: ignore USB2 hub issues

This issue happened again on CML_HEL_RT5682 in case check-suspend-resume-50.sh, in CI daily test ID1828 on 2021-01-26:

kernel-log-check: revise ignore_str for usb hub

I think this is related to USB hub or card devices, because we never see this in PRC.

kernel-log-check: revise ignore_str for usb hub

This issue happened again on CML_HEL_RT5682 in case check-suspend-resume-50.sh, in CI daily test ID1828 on 2021-01-26:

What happened there is actually a cascade of 3 USB errors and the one above is the second one. In general it's not worth looking past the first error.

Before this USB error, there was another, previous USB failure two test earlier during the check-kmod-load-unload.sh audio test. I think it's already reported in another bug, maybe #567?

After this one there was a 3rd error with the USB network adapter in the same, suspend-resume test:

Using unreliable USB devices seems like a total waste of time. How many more ignore_str until we understand this?
