Flipping GPIO 11 doesn't blink the LED on #BL602 #NuttX ... Let's investigate 🤔

https://github.com/lupyuen/incubator-nuttx/blob/master/boards/risc-v/bl602/bl602evb/include/board.h#L45-L53

How shall we flip GPIO 11, the Blue LED on PineCone #BL602? We edit the #NuttX GPIO Pin Definition ... And GPIO 11 becomes "/dev/gpout1"

GPIO Demo calls "ioctl" to control the GPIO Pins on #BL602 #NuttX

https://github.com/apache/incubator-nuttx-apps/blob/master/examples/gpio/gpio_main.c

"help" shows the commands available on #BL602 #NuttX ... "ls /dev" reveals the GPIO Pins that we may control ... Yep everything looks like a file!
