[PATCH v2 7/7] Revert "genirq/msi: Provide constants for PCI/IMS support"

[Bjorn Helgaas <helgaas@kernel.org>]

From: Bjorn Helgaas <bhelgaas@google.com>

This reverts commit e23d4192bf9b612bce5b24f22719fd3cc6edaa69.

IMS (Interrupt Message Store) support appeared in v6.2, but there are no
users yet.

Remove it for now.  We can add it back when a user comes along.
