Separated kernel API dependency exports into their own patch. Removed the vmd irq domain hierarchy, and instead use a msi irq domain. This pushed all the irq initialization and teardown handling into the irq_chip implementation and reduced kernel dependencies. Using devm_request_irq instead of an irq flow handler. This moves the irq life management to the devres API which simplifies teardown. Implemented a smarter method of selecting the VMD vector to share. Lots style fixes/updates and additional code comments. The one review comment I have not fixed is the affinity hint. We are still developing a way to better handle this, so have left it as a error returning stub. It's less than optimal, but isn't more harmful than that.
