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)

csr: use external csr_readl()/csr_writel() if present
...
If the variable CSR_ACCESSORS_DEFINED is set, then use external
csr_readl() and csr_writel() instead of locally-generated inline
functions.
With this patch, csr.h can be used with etherbone.h and litex_server to
prototype drivers remotely.

csr: use readl()/writel() accessors for accessing mmio
...
Instead of directly dereferencing pointers, use variants on readl()/writel().
This way we can replace these functions with others for remote access
when writing drivers and code outside of the litex environment.
