Document the 31-Pin MIPI CSI (4-lane), 15-Pin MIPI CSI (2-lane) and 7-Pin I2S header pinouts, including IO levels, so users can check wiring and level compatibility.

背景
docs/accessories/display/hdmi-in-to-mipi-csi2目前只有产品规格(4-lane / 2-lane MIPI CSI、I2S 音频、辅助信号)和机械尺寸,但没有接口线序。用户实际接线时无法确认每个引脚对应什么信号、电平是多少,尤其是需要单独接 I2S 音频的场景。本 PR 依据内部硬件线序资料,为转接板补充完整的接口定义。
改动内容
在
docs/accessories/display/hdmi-in-to-mipi-csi2/README.md新增「接口线序 / Pinout」一节(位于「机械尺寸」与「配件清单」之间),包含三张表:RK628_INT/RK628_Plugin_DET/RK628_Reset、3.3V 与 5V 电源、NC 引脚RK628_Plugin_DET/RK628_INT/ GND每张表按「引脚 / 信号 / 电平 / 说明」列出,并在末尾补充三条注意事项:
RK628_Plugin_DET和RK628_INT在 31-Pin 上是 1.8V、在 7-Pin 排针上是 3.3V,接线时需注意电平匹配NC的引脚未连接,保持悬空,不要与其他信号短接减少什么误解
DET/INT(两个接口电平不同)说明
