### LCD_GPIO_Init2p8

`void LCD_GPIO_Init2p8(st_7789_io_cfg_t *io_cfg)`

- function description:
  
   - lcd gpio init。
- param:
    - st_7789_io_cfg_t
    ```c

        typedef struct
        {
            st_7789_io_t reset;
            st_7789_io_t spi_cs;
            st_7789_io_t spi_clk;
            st_7789_io_t spi_mosi;
            st_7789_io_t bl_en;		// back light enable
            st_7789_io_t lcd_en;	        // lcd enable	
        }st_7789_io_cfg_t;	  
	```
  
    - st_7789_io_t
    ```c
      typedef struct
      {
          em_io_type io_type;
          gpio_dev_t gpio;		        // config this field if io_type is gpio
          uint8_t ao_gpio_id;		// config this field if io_type is ao_gpio
      }st_7789_io_t;

    ```
	- em_io_type
  	
    ```c

        typedef enum

        .spi_clk.gpio.pin = SDSLV_MUX, 
        .spi_clk.gpio.pin_func = GPIO_MUX,

        .spi_mosi.io_type = GPIO_7789,
        .spi_mosi.gpio.port = PC16,
        .spi_mosi.gpio.config = OUTPUT_OPEN_DRAIN_NO_PULL,
        .spi_mosi.gpio.priv = 0, 
        .spi_mosi.gpio.pin = SDSLV_MUX, 
        .spi_mosi.gpio.pin_func = GPIO_MUX,	

        .bl_en.io_type = AOGPIO_7789,

        .lcd_en.io_type = AOGPIO_7789,
        .lcd_en.ao_gpio_id = 8, 
    };

    LCD_GPIO_Init2p8(&g_lcd_io_cfg);
