* 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

* Revert "FT81x: Replace gpio_pad_select_gpio with esp_rom alias"
This reverts commit 8c7bc42140.
* esp_lcd_backlight: Handle different versions of ESP-IDF
* esp_lcd_backlight: Add missing header
* lvgl_spi_conf: Add missing include
* uc8151d/jd79653a: Fix compilation error when logging is enabled
* FT81x: Handle ESP-IDF v4.3 rom_gpio
* FT81x: Add missing include
* Compilation error when SPI Host is not selected
* lvgl_helpers.c: Enable init_ft81x only when FT81X is selected
* adcraw: Handle gpio_pad_selection on multiple ESP-IDF versions
* esp_lcd_backlight: Remove esp_rom functions
* FT81x: Remove esp_rom functions
* adcraw: Remove esp_rom functions
* [lvgl_helpers] Cleanup and misc code cleanup
Checks for SPI_HOST_MAX symbol before using it.
Rename lvgl_driver_init to lvgl_interface_init because it now only initialize
the interface bus for display drivers, we still need to remove the indev
drivers from here.
Use types defined in spi_types.h for spi host (spi_host_device_t) and
spi dma channels (spi_dma_chan_t).
Also add a couple of symbols to avoid using magic numbers
* [lvgl_helpers] Reduce usage of if defined in lvgl_interface_init
* [lvgl_helpers] Fix spi dma channel for ESP-IDF versions <= 4.2
* [examples] Update hello_world to call lvgl_interface_init
* Add lvgl_get_display_buffer_size helper
This helper will allow us to get the calculated display buffer size instead of using a global symbol.
* Implement lvgl_get_display_buffer_size
This API will be used to get the calculation of display buffer size.
* Delete DISP_BUF_SIZE symbols
The same functionality is handled by lvgl_get_display_buffer_size
* Move SPI max transfer size calculation to helper
Use calculate_spi_max_transfer_size to calculate the SPI max transfer size for the SPI master configuration
* Remove SPI_BUS_MAX_TRANSFER_SZ definition
Same functionality is now handled in calculate_spi_max_transfer_size
* Update display buffer size calculation
Use lvgl_get_display_buffer_size helper instead of DISP_BUF_SIZE symbol
* Update example to LVGL v8
Add comments about changes from:
- LVGL v7 to LVGL v8
- Configuration helpers and display drivers
* Update lvgl_helpers.c
* Update sh1107 driver
* Update EVE driver
Check for symbols used in previous implementations before trying to use them
and add a fallback temporary implementation when not found.
The falback implementation isn't tested with hardware.
Symbols:
- DISP_BUF_SIZE
- SPI_TRANSFER_SIZE
* Update uc8151d driver
* Update jd79653a driver
* Update ra8875 driver
* Update il3820.h
Check for LV_HOR_RES_MAX and LV_VER_RES_MAX before trying to use them
* Update lvgl_helpers.c
Check for ESP-IDF version before trying to use spi_dma_chan_t type
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.
