Cleanup lvgl_helpers (#171)

Browse source 
* 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

* lvgl_interface_init: Initial cleanup

* lvgl_helpers: Replace spi_common_dma_t values with integers

This enum was introduced in ESP-IDF v4.3 and can't be used in older versions
of ESP-IDF.

* lvgl_helpers: Rearrange includes

* lvgl_tft: Remove gpio_pad_select_gpio from drivers init functions

* lvgl_helpers: Use spi_host_device_t from v4.3 onwards

* esp_backlight: Replace gpio with esp_rom API

* il3820: Remove GPIO initialization from driver init

* FT81x: Replace gpio_pad_select_gpio with esp_rom alias

* Fix esp_rom_gpio.h path

* FT81x: Fix esp_rom_gpio.h path

* adcraw: Disable usage of gpio_pad_select_gpio

* GC9A01: Remove usage of gpio_pad_select_gpio

* ra8875: Remove usage of gpio_pad_select_gpio

* Revert "esp_backlight: Replace gpio with esp_rom API"

This reverts commit 24e4bf0b88.

* 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
