PCI/MSI: pci-tegra: convert to MSI domains
In anticipation of the removal of the msi_controller structure,
convert the Tegra host controller driver to MSI domains.
We end-up with the usual two domain structure, the top one being
a generic PCI/MSI domain, the bottom one being Tegra-specific and
handling the actual HW interrupt allocation.
TODO:
- tegra_pcie_msi_irq should be a chained handler with its own
irqchip, instead of a normal interrupt handler
- Handling flow for MSIs should be handle_edge_irq instead
of handle_simple_irq
- Multi-MSI handling
- Use the AFI_MSI_EN_VECx registers to provide MSI masking
even when !MSI-X is used
