gpu: nvgpu: fix non-IOMMU mappings

Browse Source 
In __nvgpu_gmmu_do_update_page_table(), and in case of non-IOMMU mappings,
we call nvgpu_sgt_get_phys() to get physical address

But this API ignores mapping attributes including l3_alloc attribute
specified by user space, and this breaks L3 cache allocations

Fix this by using g->ops.mm.gpu_phys_addr() which also considers the
mapping attributes and returns appropriate physical address
