net: tulip: turn compile-time warning into dev_warn()
The tulip driver causes annoying build-time warnings for allmodconfig builds for all recent architectures: dec/tulip/winbond-840.c:910:2: warning: #warning Processor architecture undefined dec/tulip/tulip_core.c:101:2: warning: #warning Processor architecture undefined! This is the last remaining warning for arm64, and I'd like to get rid of it. We don't really know the cache line size, architecturally it would be at least 16 bytes, but all implementations I found have 64 or 128 bytes. Configuring tulip for 32-byte lines as we do on ARM32 seems to be the safe but slow default, and nobody who cares about performance these days would use a tulip chip anyway, so we can just use that. To save the next person the job of trying to find out what this is for and picking a default for their architecture just to kill off the warning, I'm now removing the preprocessor #warning and turning it into a pr_warn or dev_warn that prints the equivalent information when the driver gets loaded.
