Nitin Kumbhar 410dcc0409 gpu: nvgpu: add secure math operations ...

Add functions which perform addition, subtraction and
multiplication of u32 and u64 types in a secure way
returning an error if operand type cannot correctly hold
the operation result.

Also, add type casting functions which handle conversions to
ensure that a conversion doesn't result in lost or misinterpreted
data.
