When the device tree is missing a correct spi slave description below
the bus, the 'set_speed' callback can be called with 'speed' == 0 Hz.
At least with cadence qspi, this leads to a division by zero.
Prevent this by initializing speed to 100 kHz in this case, as is
done in 'dm_spi_claim_bus'.
Better go-with default baudrate if speed == 0 this what usually does
in remaining drivers.
That's what I did. I set a default value of 100 kHz. The difference
seems to me that the remaining drivers are host drivers whereas I was
trying to fix an invalid declaration of a df chip.
