[brcm47xx]: bcma: do not initialize deactivated PCIe cores

Browse Source 
Before it was tried to initialize the deactivated PCIe core in client
mode, but this causes the SoC to hang. Just do not initialize it at all
and ignore the core it is not working and nothing is connected to it
when the specific bit is set in the boardflags.
