The PCI error recovery always resets the link for a frozen state, so the
port driver should return that a reset is required for its result. This
will get the .slot_reset() callback invoked, which is necessary to
restore the port's config space. Without this, the driver had been
relying on downstream drivers to return this status.

Function cdns_pcie_host_map_dma_ranges() iterates over a PCIe host bridge
DMA ranges using the resource_list_for_each_entry() iterator, returning an
error if cdns_pcie_host_bar_config() fails.

49e427e6 ("Merge branch 'pci/host-probe-refactor'") botched a merge so
it *always* returned after the first DMA range, even if no error occurred.

Fix the error checking so we return early only when an error occurs.

In case a PCI host driver's probe is deferred, the same I/O range may be
allocated again, and be ignored, causing a memory leak.

Fix this by (a) letting logic_pio_register_range() return -EEXIST if the
passed range already exists, so pci_register_io_range() will free it, and
by (b) making pci_register_io_range() not consider -EEXIST an error

The PCIe Bandwidth Change Notification feature logs messages when the link
bandwidth changes.  Some users have reported that these messages occur
often enough to significantly reduce NVMe performance.  GPUs also seem to
generate these messages.

We don't know why the link bandwidth changes, but in the reported cases
there's no indication that it's caused by hardware failures.

Remove the bandwidth change notifications for now.  Hopefully we can add
this back when we have a better understanding of why this happens and how
we can make the messages useful instead of overwhelming.

Remove comparisons with PCIBIOS_SUCCESSFUL and check only for non-zero.  It

4.5.1, _OSC is required for PCIe hierarchies.  If _OSC is absent or fails,
the OS must not attempt to use any of the features defined for _OSC.  That
