* lvgl_spi_conf: Define TFT_SPI_HOST even when no SPI is choosen
* lvgl_helpers: Let the SPI driver choose SPI DMA Channel
Use SPI_DMA_CH1 only on ESP32 target.
* lvgl_helpers: Move FT81X initialization to helper

Allows to not allocate a GPIO for display reset: some may have that pin tied or attached to a Power management IC.
Supersedes PR from @usedbytes doing same but only for IL9341, this is for all supported displays.
