Add board support for the GigaDevice GD32F470Z-START (GD32F470ZIT6 minimal system board). The GD32F470ZIT6 is a Cortex-M4F MCU running at up to 240 MHz with 2048 KiB of Flash and 768 KiB of SRAM. The board enables the following peripherals: - GPIO: two user LEDs (PA1, PA2, active-low) and two user buttons (KEY0 on PC1, WK_UP on PA0, active-high) - USART0: console on PA9/PA10 (CH340X, 115200 8N1) - I2C0: AT24C02 EEPROM on PB6/PB7 - SPI4: W25Q128 NOR flash on PF6-PF9 Assisted-by: GitHubCopilot:deepseek-v4-pro-0813 Signed-off-by: Zhijian Han <hanzhijian1991@gmail.com>

Summary
Add board support for the GigaDevice GD32F470Z-START (GD32F470ZIT6 minimal system board).
Board details
Testing
The board was verified on real hardware:
samples/basic/blinky(LED1 blinks as expected)samples/hello_world(serial output via CH340X confirmed at 115200 8N1)samples/basic/buttonandsamples/drivers/spi_flashsuccessfullyNote: SEGGER J-Link does not yet include the GD32F470 device in its database,
so the J-Link runner uses GD32F450ZK as a compatible stand-in (same core, flash
and SRAM base addresses, and identical CPU TAP ID).
