arm: Make translateFunctional override the base implementation.

Now that translateFunctional is a virtual function, having an extra
parameter with a default value makes the compiler fall through to the
base implementation instead of overriding it. This change removes the
default value for the extra parameter, and adds a small wrapper with
the correct signature which overrides the base implementation and calls
the full version with the previously default value for the extra
parameter. To callers this will look like the same thing, but the
the right function will get called.

This was what was already being done for transateAtomic and
translateTiming.
