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

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.

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.
