Is your feature request related to a problem?

when LCD_RGB_ISR_IRAM_SAFE is enabled in SDK config, the following error is given:
lcd_panel.rgb: esp_lcd_rgb_panel_register_event_callbacks(397): on_frame_buf_complete callback not in IRAM
ESP_ERROR_CHECK failed: esp_err_t 0x102 (ESP_ERR_INVALID_ARG) at 0x420405fc

Describe the solution you'd like

add IRAM attribute to vsync ready callback so can be used with LCD_RGB_ISR_IRAM_SAFE enabled

proposed change
line 68 (esp_lvgl_port_disp.c)
static bool lvgl_port_flush_rgb_vsync_ready_callback(esp_lcd_panel_handle_t panel_io, const esp_lcd_rgb_panel_event_data_t *edata, void *user_ctx);
to
static IRAM_ATTR bool lvgl_port_flush_rgb_vsync_ready_callback(esp_lcd_panel_handle_t panel_io, const esp_lcd_rgb_panel_event_data_t *edata, void *user_ctx);

and
line 446 (esp_lvgl_port_disp.c)
static bool lvgl_port_flush_rgb_vsync_ready_callback(esp_lcd_panel_handle_t panel_io, const esp_lcd_rgb_panel_event_data_t *edata, void *user_ctx)
to
static IRAM_ATTR bool lvgl_port_flush_rgb_vsync_ready_callback(esp_lcd_panel_handle_t panel_io, const esp_lcd_rgb_panel_event_data_t *edata, void *user_ctx)
