[PATCH 5/5] tty: srmcons: remove 'str_cr' and use string directly

[Jiri Slaby (SUSE)]

'str_cr' contains a single character: \r. There is no need to declare it
as array. Instead, pass the character (as a string) to callback_puts()
directly. This ensures the string is in proper .rodata (const) section
and makes the code more obvious.

Notes:
    [v2]
      pass "\r" directly to callback_puts() as Richard suggests
      spell correct \r in the commit log as Ilpo noticed
