serial: doc: Re-add paragraph documenting uart_console_write()

Browse Source 
Commit 834392a7d9 ("serial: doc: Un-document non-existing
uart_write_console()") removed a paragraph about a helper function that
seemed to never exist.

Peter Hurley pointed out that the function does exist, but is called
differently. Re-add the paragraph, with the function name corrected.

arguments (uart_parse_options). arguments (uart_parse_options).
There is also a helper function (uart_console_write) which performs a
character by character write, translating newlines to CRLF sequences.
Driver writers are recommended to use this function rather than implementing
their own version.
