tty: atmel_serial: Use of_property_present() for non-boolean properties

Browse Source 
The use of of_property_read_bool() for non-boolean properties is
deprecated in favor of of_property_present() when testing for property
presence.

As of_property_present() returns a boolean, use that directly
and simplify the code a bit while we're here.
