Subject: [PATCH v2] PCI/MSI: Enable PCI_MSI_IRQ_DOMAIN support for Microblaze

From: Kuldeep Dave <kuldeep.dave@...inx.com>

Add Microblaze as an arch that supports PCI_MSI_IRQ_DOMAIN and add
generation of msi.h in the Microblaze arch.

The same change has been done by commit 251a44888183
("riscv: include generic support for MSI irqdomains")
and by commit 2a9af0273c1c
("PCI/MSI: Enable PCI_MSI_IRQ_DOMAIN support for RISC-V").
