Clean up obsoleted x86 interrupt manangement code and interfaces

The patch set "[Patch Part1 v8 00/37] Convert x86 to hierarchy irqdomain and stacked irqchip" at http://www.spinics.net/lists/kernel/msg1967024.html
has converted x86 interrupt managment to use hierarchy irqdomain and stacked irqchip. And this is the following-on patch set to clean up code and interfaces obseleted by previous patch set.

With the these two patch sets combined, we have

That's good, the refactor improves code maintanence with less code.

Main changes since last reviewed version:
1) rebased onto v4.0-rc6
2) add patch 33 to avoid memory allocation/free when assigning CPU vector

Regards,
Gerry
