The Oops is caused when `pci_stop_dev()` tries to remove a non-existing device-tree node associated with the pci_dev that was earlier hot-plugged and was attached under a pci-bridge. The PCI dev header `dev->hdr_type` being 0, results a conditional check done with `pci_is_bridge()` into false. Consequently, a call to `of_pci_make_dev_node()` to create a device node is never made. When at a later point in time, in the device node removal path, a memcpy is attempted in `__of_changeset_entry_invert()`; since the device node was never created, results in an Oops due to kernel read access to a bad address. To fix this issue the patch updates `pci_stop_dev()` to ensure that a call to `of_pci_remove_node()` is only made for pci-bridge devices.

Stanimir has already submitted a patch "Add PCIe support for bcm2712" for the RPi version of the SOC. It is hoped that Stanimir will allow us to submit this series first and subsequently rebase his patch(es). The largest commit, "Refactor for chips with many regular inbound BARs" affects both the STB and RPi SOCs. It allows for multiple inbound ranges where previously only one was effectively used. This feature will also be present in future STB chips, as well as Broadcom's Cable Modem group.
