gpu: nvgpu: Remove mm.get_iova_addr
Remove the mm.get_iova_addr() HAL and replace it with a new HAL called mm.gpu_phys_addr(). This new HAL provides the real phys address that should be passed to the GPU from a physical address obtained from a scatter list. It also provides a mechanism by which the HAL code can add extra bits to a GPU physical address based on the attributes passed in. This is necessary during GMMU page table programming. Also remove the flags argument from the various address functions. This flag was used for adding an IO coherence bit to the GPU physical address which is not supported.
