Xenial SRU - CAPI: CGZIP AFU contexts do not receive interrupts after heavy afu open/close

[Tim Gardner]

The fix commit 2bc79ffcbb817873cc43d63118008ab75181b73d ('cxl: Poll for
outstanding IRQs when detaching a context') requires a bunch of
scaffolding. Since we already have a mix of interdependent cxl and
cxlflash patches I decided to just all cxl/cxlflash patches up to and
including the fix commit. Regression testing is straightforward since
this driver only exists on one platform and architecture.

See attached pull request.
