[PATCH] selftests/powerpc/eeh: disable kselftest timeout setting for eeh-basic
The eeh-basic test got its own 60 seconds timeout (defined in commit 414f50434aa2 "selftests/eeh: Bump EEH wait time to 60s") per breakable device. And we have discovered that the number of breakable devices varies on different hardware. The device recovery time ranges from 0 to 35 seconds. In our test pool it will take about 30 seconds to run on a Power8 system that with 5 breakable devices, 60 seconds to run on a Power9 system that with 4 breakable devices. Thus it's better to disable the default 45 seconds timeout setting in the kselftest framework to give it a chance to finish. And let the test to take care of the timeout control.
