Merge branch 'bnx2x-Perform-IdleChk-dump'

Sudarsana Reddy Kalluru says:

====================
bnx2x: Perform IdleChk dump.

Idlechk test verifies that the chip is in idle state. If there are any
errors, Idlechk dump would capture the same. This data will help in
debugging the device related issues.
The patch series adds driver support for dumping IdleChk data during the
debug dump collection.
Patch (1) adds register definitions required in this implementation.
Patch (2) adds the implementation for Idlechk tests.
Patch (3) adds driver changes to invoke Idlechk implementation.

Changes from previous version:
-------------------------------
v3: Combined the test data creation and implementation to a single patch.
v2: Addressed issues reported by kernel test robot.
