softpipe: remove backwards dependency from tilecache to softpipe

The tile cache is a utility, it shouldn't know anything about the
entity which is making use of it (ie softpipe).

Remove softpipe parameter to all the tilecache function calls, and
also remove the need to keep a softpipe pointer in the sampler structs.
