Build, flash and run #NuttX ... Our SPI Test Driver appears as "/dev/spitest0"! 🎉

https://github.com/lupyuen/incubator-nuttx/blob/newdriver/drivers/rf/spi_test_driver.c

Update the Makefile "Make.defs" ... So that #NuttX will build our SPI Test Driver

https://github.com/lupyuen/incubator-nuttx/blob/newdriver/drivers/rf/Make.defs#L33-L37

Here's what happens when we make a boo-boo and #NuttX won't start

Remember to enable "SPI0" and "SPI Character Driver" in #NuttX ... Or our SPI Test Driver won't start

https://github.com/lupyuen/incubator-nuttx/blob/newdriver/drivers/rf/spi_test_driver.c

Our SPI Test Driver for #NuttX appears in "make menuconfig"!

https://github.com/lupyuen/incubator-nuttx/blob/newdriver/drivers/rf/Kconfig#L22-L27

Add our SPI Test Driver to #NuttX Kconfig

https://github.com/lupyuen/incubator-nuttx/blob/newdriver/drivers/rf/Kconfig#L22-L27

At #NuttX Startup, register our SPI Test Driver as "/dev/spitest0"
