[Skiboot] [PATCH] Revert "core/ipmi: Set interrupt-parent property"

[Stewart Smith]

This reverts commit d997e482705d9fdff8e25fcbe07fb56008f96ae1.

A problem was found with pre 4.2 linux kernels where a spurious WARNING
would be emitted. This change doesn't matter enough to scare users
so we can just revert it.
