Function: free_physical

C Prototype	aclError aclrtFreePhysical(aclrtDrvMemHandle handle)
Python Function	ret = acl.rt.free_physical(handle)
Function Usage	Frees the physical memory allocated by the acl.rt.malloc_physical call. The Atlas 200/300/500 Inference Product does not support this API.
Input Description	handle: handle of the physical address to be released.
Return Value	ret: int, error code. 0 indicates success. Other values indicate failure.
Restrictions	This API is not supported in Ascend RC form. If the physical memory is mapped to virtual memory, you need to unmap them by calling acl.rt.unmap_mem before freeing the physical memory.
