device: Move MSI related data into a struct
The only unconditional part of MSI data in struct device is the irqdomain
pointer. Everything else can be allocated on demand. Create a data
structure and move the irqdomain pointer into it. The other MSI specific
parts are going to be removed from struct device in later steps.
