irqchip: Convert all platform MSI users to the new API

KAGA-KOKO · KAGA-KOKO · commit 14fd06c776b5 · 2024-02-15T17:55:40.000+01:00
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.
