genirq/msi: Move xarray into a separate struct and create an array

Browse source

The upcoming support for multiple MSI domains per device requires storage
for the MSI descriptors and in a second step storage for the irqdomain
pointers.

Move the xarray into a separate data structure msi_dev_domain and create an
array with size 1 in msi_device_data, which can be expanded later when the
support for per device domains is implemented.
