Inochi Amaoto 7ee4a5a2ec irqchip/sg2042-msi: Set MSI_FLAG_MULTI_PCI_MSI flags for SG2044
The MSI controller on SG2044 has the ability to allocate multiple PCI MSI
interrupts. So the PCIe controller driver can use this feature if the
hardware supports multiple PCI MSI interrupts.

Add the MSI_FLAG_MULTI_PCI_MSI flag to the supported_flags of SG2044
msi_parent_ops to enable this functionality.

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 reStructuredText 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.
