Nam Cao 2743cf75f7 powerpc, ocxl: Fix extraction of struct xive_irq_data 
Commit cc0cc23bab ("powerpc/xive: Untangle xive from child interrupt
controller drivers") changed xive_irq_data to be stashed to chip_data
instead of handler_data. However, multiple places are still attempting to
read xive_irq_data from handler_data and get a NULL pointer deference bug.

Update them to read xive_irq_data from chip_data.

Non-XIVE files which touch xive_irq_data seem quite strange to me,
especially the ocxl driver. I think there ought to be an alternative
platform-independent solution, instead of touching XIVE's data directly.
Therefore, I think this whole thing should be cleaned up. But perhaps I
just misunderstand something. In any case, this cleanup would not be
trivial; for now, just get things working again.
