titan requires prototype(fast) functions for translation ports

Submitted by Kristof Szabados

Link to original bug (#537177)

Description

In it current implementation titan requires function used as translation frunctions to have a prototype(fast) attribute. Otherwise an error is reported: " In type mapping: In function' mapping: error: The referenced function @PortTranslation.char_to_hex' does not have `prototype' fast attribute "

But the standard does not list such a requirement for the usable functions.
