SPI Backlight pin on IO9 gives conflict with boot mode selection

[bartkodden]

Somehow the SPI TFT display connects IO9 to ground or 3v3. This prevents the ESP32 to enter flash boot

Still looking for a good fix. currently I removed the SPI reset connection and routed that to SPI backlight.
However I am not too happy with this solution. Will need further investigation.
