bcma: fix access to host_pdev for PCIe devices
bus->host_pdev is part of a union so bus->host_pdev != NULL is probably also true for PCIe devices, because there it accesses bus->host_pci. If we access the dev member at the offset defined in struct platform_device in struct pci_dev instead we probably get something else. This patch adds a new function which returns the host dev struct and NULL if we do not have a host dev. When this gets registered on MIPS brcm47xx we do not have a host dev in some situations. This function could also be used in other places. This problem was introduced in this commit: commit cae761b5a6bdc597ba476a040fdcd5b4bc559b85 Author: Rafa?
