[PATCH v4 0/5] of/irq: Misc msi-parent handling fixes/clean-ups

[Lorenzo Pieralisi <lpieralisi@kernel.org>]

This is series is a follow up to [1] - with additional patches that are
addressing Rob's feedback (pcie-layerscape-gen4 was removed from the
kernel, Yay !) and other bits and bobs I noticed while staring at the code.

Patch (1) is a fix and technically we would like to get it in v6.18 please.

Patch (4) is compile-tested only, I can not run it on HW, I do not have it,
Scott, Ray please test it if you can.

v3 -> v4:
	- Addressed Rob's review
	- Added trailers
	- Rebased against v6.18-rc2

v2 -> v3:
	- Added additional patch to export of_msi_xlate()
	- Addressed review feedback
