Only a personal taste, but since we keep calling it "device MSI",
which it really is, I find it slightly odd to name the token
"DEVICE_IMS".

From what I understand, IMS is PCIe specific. Platform (and by
extension device) MSI extends far beyond PCIe. So here, DEVICE_MSI
would make a lot more sense and avoid confusion.

But hey, I don't have much skin in this game, and I can probably
mentally rotate the acronym...
