Use the same method as 7e6086d9e54a159a6257c02bb7fc5805c614aad2 does for gpios:
Use alias to identify the spi port, and then specify the base via the port id.
If alias is not defined in DT, allocate the base dynamically.

This sounds like a fix userspace and/or complete your DT conversion
problem...

Well, it may lead to problems in userspace and does lead to problems with an
incomplete DT support, but there are only so many hours in a day...
