The spi_get_bus_and_cs() may be called on the same bus and chipselect

fails to notify the controller of such a configuration change. Call
spi_set_speed_mode() in case bus frequency or bus mode changed to let
the controller update the configuration.
The problem can easily be triggered using the sspi command:
=> sspi 0:0@1000
=> sspi 0:0@2000
Without this patch, both transfers happen at 1000 Hz. With this patch,
the later transfer happens correctly at 2000 Hz.

So, very reliably I can make:

happen locally as well building with clang. It's not obvious to me why
the test now fails however.
Can you please be more specific / clear ? I have no idea what those 300
lines of cryptic output mean, nor what are you trying to say by the
above, sorry.
