pnv_opal_pci_msi_eoi() is called from KVM to EOI passthrough interrupts when in real mode. Adding MSI domain broke the hack using the 'ioda.irq_chip' field to deduce the owning PHB. Fix that by using the IRQ chip data in the MSI domain. The 'ioda.irq_chip' field is now unused and could be removed from the pnv_phb struct.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
