[RFC PATCH 02/15] genirq/msi: Provide DOMAIN_BUS_MSI_REMAP

Provide a domain bus token for the upcoming support for the RISC-V
IOMMU interrupt remapping domain, which needs to be distinguished
from NEXUS domains. The new token name is generic, as the only
information that needs to be conveyed is that the IRQ domain will
remap MSIs, i.e. there's nothing RISC-V specific to convey.
