fix 3.5 backlight and GT911 for cyd_35r.

TFT_BL was wrongly GPIO21 (GT911 INT); use GPIO27, DRAW_BUF_DIV=20, and export firmware/cyd_35r.

# 预编译固件(可随时刷写)
| 目录 | 板子 |
|------|------|
| [`cyd/`](cyd/) | **2.8"** CYD ESP32-2432S028R(ILI9341) |
| [`cyd_35r/`](cyd_35r/) | **3.5"** CYD ESP32-3248S035C(ST7796 + GT911) |
功能:**WiFi 配网**(屏上扫网 + SoftAP 门户)
版本信息见各目录下 `VERSION.txt`。
也可在 [`../../cydweb`](../../cydweb)(CYD Flasher)里通过浏览器串口刷写本目录固件。
## 直接刷写(无需重新编译)
1. USB 连接板子
2. 执行:
```powershell
cd firmware\cyd # 3.5": firmware\cyd_35r
.\flash.ps1
# 或指定端口
.\flash.ps1 -Port COM3
```
也可运行 `flash.bat`。
依赖其一即可:
- 已安装 PlatformIO(`pio`,自带 esptool)
- 或 `pip install esptool`
## 手动 esptool
```bash
esptool.py --chip esp32 --port COM3 --baud 921600 write_flash -z ^
--flash_mode dio --flash_freq 40m --flash_size 4MB ^
0x1000 bootloader.bin ^
0x8000 partitions.bin ^
0xe000 boot_app0.bin ^
0x10000 firmware.bin
```
## 从源码重新打包进本目录
在仓库根目录:
```powershell
.\firmware\export_from_build.ps1 # 2.8 -> firmware/cyd
.\firmware\export_from_build.ps1 -Env cyd_35r # 3.5 -> firmware/cyd_35r
# 仅复制、不编译:
.\firmware\export_from_build.ps1 -Env cyd_35r -SkipBuild
```
