Alex Elder ae1d72f977 net: ipa: add driver shutdown callback ... A system shutdown can happen at essentially any time, and it's possible that the IPA driver is busy when a shutdown is underway. IPA hardware accesses IMEM and SMEM memory regions using an IOMMU, and at some point during shutdown, needed I/O mappings could become invalid. This could be disastrous for any "in flight" IPA activity. Avoid this by defining a new driver shutdown callback that stops all IPA activity and cleanly shuts down the driver. It merely calls the driver's existing remove callback, reporting the error if it returns one.
