[brcm47xx]: bcma: use fallback sprom if sprom on card was not valid
Sometimes the PCIe card indicates that it has a sprom somewhere and we are able to read the memory region, but it is empty and not valid. In these cases we should try to use the fallback sprom as a last chance. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@33601 3c298f89-4303-0410-b956-a3cf2f4a3e73
