gpu: nvgpu: resolve MISRA 10.3 violations

MISRA rule 10.3 prohibits implicit assigning of u64 to u32. The nvgpu was
assigning the value returned by ARRAY_SIZE which is a u64 to a u32. This
value was then returned in a function defined by gpu_ops.

This patch changes the return type for these gpu_ops to u64 and updates
the functions that implement the functions and lastly the saved value. This
removes the violation in this instance.
