Bug description:
[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)

last sleep cycle, got 65.64%. (x 9)
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.
