cciss: PCI power management reset for kexec
The kexec kernel resets the CCISS hardware in three steps:
1. Use PCI power management states to reset the controller in the
kexec kernel.
2. Clear the MSI/MSI-X bits in PCI configuration space so that MSI
initialization in the kexec kernel doesn't fail.
3. Use the CCISS "No-op" message to determine when the controller
firmware has recovered from the PCI PM reset.
