PCI: mvebu: add support for MSI

Browse source

This commit adds support for Message Signaled Interrupts in the
Marvell PCIe host controller. The work is very simple: it simply gets
a reference to the msi_chip associated to the PCIe controller thanks
to the msi-parent DT property, and stores this reference in the
pci_bus structure. This is enough to let the Linux PCI core use the
functions of msi_chip to setup and teardown MSIs.
