[PATCH v2 4/4] irqchip/sg2042-msi: Set MSI_FLAG_MULTI_PCI_MSI flags for SG2044

[Inochi Amaoto <inochiama@gmail.com>]

The MSI controller on SG2044 has the ability to allocate multiple
PCI MSI interrupts. So the PCIe controller driver can use this
feature if it also supports multiple PCI MSI interrupts.

Add MSI_FLAG_MULTI_PCI_MSI flag for the supported_flags of
SG2044 msi_parent_ops so the PCIe controller driver can use
this feature if it also supports this feature.
