PCI: endpoint: pci-ep-msi: Refactor doorbell allocation for new backends
Prepare pci-ep-msi for non-MSI doorbell backends.
Factor MSI doorbell allocation into a helper and extend struct
pci_epf_doorbell_msg with:
- irq_flags: required IRQ request flags (e.g. IRQF_SHARED for some
backends)
- type: doorbell backend type
- bar/offset: pre-exposed doorbell target location, if any
Initialize these fields for the existing MSI-backed doorbell
implementation.
Also add PCI_EPF_DOORBELL_EMBEDDED type, which is to be implemented in a
follow-up patch.
No functional changes.
