Subject: [PATCH v4 0/5] Altera PCIe host controller driver with MSI support

This is the 4th version of patch set to add support for Altera PCIe host
controller with MSI feature on Altera FPGA device families. This patchset
mainly resolve comments from Marc Zyngier in v3.

It is based on patch series from Marc Zyngier "Per-device MSI domain &
platform MSI" [1] to get rid of struct msi_controller.

v3->v4 changes:
- pcie-altera: change to incremental count for loop
- pcie-altera: add udelay when polling
- pcie-altera: return -ENOMEM for irq_domain_add_linear error
- pcie-altera-msi: add WARN_ON(nr_irq) != 1
- update error handling for platform_get_resource_byname
