bcma: add check if sprom is available before accessing it.

The SoCs like the bcm4716 do not have a sprom on the bcma bus like a
pcie device. It stores the values in some partition on flash memory.
For ssb this informations are read out in the bcm47xx arch code,
something like that should also be implemented for bcma. Without this
patch bcma panics on SoCs.
