[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.

V2:
- propose for B/E/U/OEM-B as well
- update V2 patch proposed to kernel mainling list to preserve fault
  tolerance as the original driver code does.
