backlight: ili9320: add missing SPI dependency

Add this missing SPI dependency and prevent the driver from building without SPI, because functions of the spi driver are used in this driver. drivers/video/backlight/ili9320.c:51: undefined reference to `spi_sync' Also, a prompt string for CONFIG_LCD_ILI9320 is added for explicit selection.
