I add a new ST7701s setting and init codes for a beautiful 480x800 4inch None-Air-Gap IPS screen. Need help to optimize it.

[hugo8873]

Hello all,
Im very new to Github and recently I test a none air gap IPS touch screen hardware, want to share what I got here with everyone.
(I need help on take a second look at my codes and wiring, since I grab codes from here and there, and some of them I don't really understand, would you take a moment to look at my init code for this screen, if there anything not so optimized? Such as the pins, data bus, etc. Appreciated.)
(And I also want to retrieve some pins for more peripherals, any idea remove some unnecessary pins?)

Screen bought from https://item.taobao.com/item.htm?spm=a1z09.2.0.0.319a2e8dE909QS&id=614606266642&_u=q1su9gba322
Having a ST7701S with 45-pin (3-SPI + RBG565) FPC connector
Touch IC: GT911

I add a new st7701_type9_init_operations[] with help from the manufacturer
static const uint8_t st7701_type9_init_operations[].txt
Add this section of code inside ~/src/display/Arduino_RGB_Display.h

Also attaching a screen data sheet.
KD040WVFPD025-C008B SPEC V1.0 .pdf

And a init code for Arduino IDE, running on ESP32-S3-Devkit-C1 N16R8
It can run with LVGL(SquarelineStudio)

`#define GFX_BL 46

Arduino_DataBus bus = new Arduino_SWSPI(GFX_NOT_DEFINED / DC /, 10 / CS /, 12 / SCK /, 11 / MOSI /, GFX_NOT_DEFINED / MISO */);

Arduino_ESP32RGBPanel rgbpanel = new Arduino_ESP32RGBPanel(
45 / DE /, 4 / VSYNC /, 5 / HSYNC /, 21 / PCLK /,
39 / R0 /, 40 / R1 /, 41 / R2 /, 42 / R3 /, 2 / R4 /,
0 / G0 /, 9 / G1 /, 14 / G2 /, 47 / G3 /, 48 / G4 /, 3 / G5 /,
6 / B0 /, 1 / B1 /, 13 / B2 /, 16 / B3 /, 8 / B4 /,
1 / hsync_polarity /, 10 / hsync_front_porch /, 8 / hsync_pulse_width /, 50 / hsync_back_porch /,
1 / vsync_polarity /, 10 / vsync_front_porch /, 8 / vsync_pulse_width /, 20 / vsync_back_porch /,
1 / pclk_active_neg /, 16000000 / prefer_speed */, false /useBigEndian/,
0 /de_idle_high/, 1 /pclk_idle_high/);

Arduino_RGB_Display gfx = new Arduino_RGB_Display(
480 / width /, 800 / height /, rgbpanel, 0 / rotation /, true / auto_flush /,
bus, 38 / RST */, st7701_type9_init_operations, sizeof(st7701_type9_init_operations));`

In addition, SPI pins:
#define TOUCH_GT911_SCL 43
#define TOUCH_GT911_SDA 44
#define TOUCH_GT911_INT 7
#define TOUCH_GT911_RST 15

And Hi @moononournation ,
Do you think it's worthwhile to add this new ST7701s type9 into your repository?
