csr.bus.Multiplexer: fix element w_stb getting stuck.
Also, don't clear shadow; this would break e.g. reading a 64-bit
CSR register through a 32-bit Wishbone bus if a code fetch happens
between the halves. Instead, clear shadow enable flag driving OR-mux.

This reverses the rename done in commit
5520e0d7. Commit
2a634b3a
introduced a Multiplexer that doesn't actually do multiplexing, so
revert that to make everything less confusing.

Application code should use Python imports similar to:
