[patch V2 13/36] genirq/msi: Consolidate MSI descriptor data
From: Thomas Gleixner <hidden>

All non PCI/MSI usage variants have data structures in struct msi_desc with only one member: xxx_index. PCI/MSI has a entry_nr member. Add a common msi_index member to struct msi_desc so all implementations can share it which allows further consolidation.
