No, unless you can provide a really compelling reason to do so, the
goal is to *not* specify Linux implementation detail things like bus
numbers in the device tree.

Instead, your code should be using spi device child nodes from the
bus, or finding the spi bus node and decoding the dynamically assigned
bus number from there.  Don't hard code spi bus numbers.
