crypto: ccree - remove unneeded casts

Browse Source 
Unneeded casts prevent the compiler from performing valuable checks.
This is especially true for function pointers.

Remove these casts, to prevent silently introducing bugs when a
variable's type might be changed in the future.

No change in generated code.
