This series introduces several improvements to the function that performs
AP queue resets:
* Breaks up reset processing into multiple smaller, more concise functions.
* Use TAPQ to verify completion of a reset in progress rather than mulitple
invocations of ZAPQ.
* Check TAPQ response codes when verifying successful completion of ZAPQ.
* Fix erroneous handling of some error response codes.
* Increase the maximum amount of time to wait for successful completion of
ZAPQ.
Change log v1 => v2:
-------------------
Remove patch 7/7 to restore original behavior since we don't know whether
interrupts are disabled when an unexpected response code is returned from
ZAPQ. (Halil)
