smilatency test is latency sensitive and does not pass deterministically when
run in QEMU environment under biosbits. Disable the test suite for now.
Example failure:
==== SMI latency test ====
Warning: touching the keyboard can affect the results of this test.
Starting test. Wait here, I will be back in 15 seconds.
[assert] SMI latency < 150us to minimize risk of OS timeouts FAIL
1us < t <= 10us; average = 1372ns; count = 10912449
Times between first few observations: 176us 1646ns 1441ns 1450ns 1462ns
10us < t <= 100us; average = 16us; count = 1187
