dm: serial: consolidate common code more

Browse source 
Commit b8893327e9 (dm: serial: Put common code into separate functions)
consolidated getc() and putc().  This commit does more puts() and tsts().

Also rename locally used functions to _serial_*() for clarification
because we have similar functions names here are there in this file.
