* update the flash driver for bcm47xx to use the stubs already in bcma
* do some misc enhancements to the flash drivers for bcm47xx
SVN-Revision: 33920
The bcma based SoCs with a ieee80211 core on the SoC and an other
connected via PCIe or USB store the sprom for the SoC with a sb/1/
prefix. The SoC with just one wifi core do not use prefixes. The
BCM4706 do not use a prefix for the SoC part at all, because the prefix
is the path to the ieee80211 core and there is non on the BCM4706.
