spi: Propagate default fwnode to the SPI controller device 



Most of the SPI controller drivers share the parent's fwnode
by explicit assignment. Propagate the default by SPI core,
so they may drop that in the code. Only corner cases may require
a special treatment and we simply (re)assign the controller's
fwnode explicitly (as it's done right now, no changes required
for that).
