When there is an actual physical sensor, the driver must implement the get info interface. The upper layer can obtain the actual physical sensor information through SNIOC_GET_INFO.
SNIOC_SET_INFO can only set the information of the local virtual sensor, which means it is bound to the local advertisement. Remote subscribers cannot set the information.
Usage:
struct sensor_device_info dev_info;
orb_ioctl(fd, SNIOC_GET_INFO, (unsigned long)(uintptr_t)&dev_info);
or:
ret = orb_set_info(fd, &dev_info);
ret = orb_get_info(fd, &dev_info);

since mmap may exist in block_operations, but truncate may not,
moving mmap beforee truncate could make three struct more compatible

- Add mmap into file_operations and remove it from ioctl definitions.
- Add mm_map structure definitions to support future unmapping
- Modify all drivers to initialize the operations struct accordingly

- Add truncate into file_operations
- Move truncate to be common for mountpt_operations and file_operations
- Modify all drivers to initialize the operations struct accordingly
