sim: serial: Send '\r\n' instead of just '\n'
...
This fixes an issue when running with the HDMI2USB firmware which
expects \r\n to come from the UART. Since the verilator adapter
is just sending \n commands cannot be executed.
Also, one minor whitespace cleanup. (could remove if needed)

If the variable CSR_ACCESSORS_DEFINED is set, then use external

functions.
With this patch, csr.h can be used with etherbone.h and litex_server to
prototype drivers remotely.
