[SRU][OEM-OSP1-B][PATCH 0/2] All PS/2 ports on PS/2 Serial add-in bracket are not working after S3

BugLink: https://bugs.launchpad.net/bugs/1866734

[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.

[Misc]
This revert a previous solution and add a rewritten one to preserve
fault tolerance as the original drive code does.
