Bug description:
  [Impact]
  PS/2 ports on PS/2 Serial add-in card do not work after S3.

  [Fix]
  The i8042 controller selftest fails while resuming, adding retry fix this 
issue.

  [Test]
  Verified on the target machine, the ps/2 keyboard keeps working after S3 test 
30 times.

  [Regression Potential]
  Low, there is a retry logic in controller selftest, but it returns directly 
if it fails to communicate with the controller. This commit make it retry 5 
times before return fails.
