mtd: st_spi_fsm: Provide documentation for boot device mask property The system configuration registers which display which device the system booted on are in the same place on all boards which support the FSM. However, the bits do shift every so slightly. To combat these we're adding a new property which supplies the necessary mask used to abstract the required information.
