Public bug reported:

[Impact]
Got the following messages while doing fwts s3 tests
    Expected /sys/power/suspend_stats/last_hw_sleep to be at least 70% of the 
last sleep cycle, got 66.10%. (x 1)
    Expected /sys/power/suspend_stats/last_hw_sleep to be at least 70% of the 
last sleep cycle, got 65.54%. (x 6)

    Expected /sys/power/suspend_stats/last_hw_sleep to be at least 70% of the

    Expected /sys/power/suspend_stats/last_hw_sleep to be at least 70% of the 
last sleep cycle, got 65.65%. (x 5)

[Fix]
AMD provides a patch to clear the smu_virt_addr table explicitly

[Test]
Runs `sudo fwts s3 --multiple=10` on AMD machines, the result.log should not 
contain the message mentioned above.

[Where problems could occur]
Clear smu_virt_addr table explicitly during setup won't introduce any 
regression.
