Making strange changes to #BL602 #NuttX SPI Driver ... Hope this works for ST7789 Display 🙏

SPI Driver for #ESP32 #NuttX flips the ST7789 Data / Command Pin as though it was GPIO ... But actually the pin is designated as SPI MISO ... Let's do the same for BL602

To flip the ST7789 Data / Command Pin on #BL602 #NuttX: We reconfigure SPI MISO as a GPIO Pin ... On the fly!
