qemu implementation of "virt" includes GICv2m. This commit allows to use
it also on ARM32 architecture.
msi.h is added because it is required by linux/msi.h
if CONFIG_GENERIC_MSI_IRQ_DOMAIN is defined. It gets enabled by the
following KConfig dependency chain:
ARM_GIC_V2M => PCI_MSI_IRQ_DOMAIN => GENERIC_MSI_IRQ_DOMAIN
