g->ops.gr.init.get_access_map() returns whitelist of register addresses that can be accessed by SET_FALCON methods when added into pushbuffer. SET_FALCON method does not need to be supported in safety. Hence install an empty register access map in safety build by adding a new flag CONFIG_NVGPU_SET_FALCON_ACCESS_MAP. Compile out g->ops.gr.init.get_access_map() and code that writes whitelist in access map buffer. Note that we still need to configure base address of access map in context image even for safety.
