The device bo is allocated from the device heap memory. (a trunk of memory dedicated to device) Rename amdxdna_gem_insert_node_locked to amdxdna_gem_heap_alloc and move related sanity checks into it. Add amdxdna_gem_dev_obj_free and move device bo free code into it. Calculate the kernel virtual address of device bo by the device heap memory address and offset.
