PCI/MSI: Export MSI mode using attributes, not kobjects
The PCI MSI sysfs code is a mess with kobjects for things that don't really need to be kobjects. This patch creates attributes dynamically for the MSI interrupts instead of using kobjects. Note, this removes a directory from sysfs. Old MSI kobjects: pci_device └── msi_irqs    └── 40    └── mode New MSI attributes: pci_device └── msi_irqs    └── 40 As there was only one file "mode" with the kobject model, the interrupt number is now a file that returns the "mode" of the interrupt (msi vs. msix).
