gpu: nvgpu: Refactor gk20a_vm_alloc_va()

Browse Source 
This function is an internal function to the VM manager that allocates
virtual memory space in the GVA allocator. It is unfortunately used in
the vGPU code, though. In any event, this patch cleans up and moves the
implementation of these functions into the VM common code.
