[patch V2 17/40] irqchip: Convert all platform MSI users to the new API

From: Thomas Gleixner
Date: Mon Nov 21 2022 - 09:50:13 EST


Switch all the users of the platform MSI domain over to invoke the new
interfaces which branch to the original platform MSI functions when the
irqdomain associated to the caller device does not yet provide MSI parent
functionality.

No functional change.
