i2c通信报错，开机插拔后恢复，怀疑和硬件或线缆连接有关

烧写user版本不复现问题

user版本开机时间较短，userdebug版本开机时间较长，可能与VX1屏幕的心跳机制有关，超过大概20s,没有写入心跳包，屏幕会自动黑屏。
VX的问题延后处理，优先VC

使用0606的userdebug版本进行验证，从一上电到kernel阶段显示驱动初始化所花时长为21秒，而VX1的lcd 内部有心跳机制，需要每隔18S写一次寄存器。
而userdebug版本开机时间较长，大于18S,导致心跳包发送超时而发生黑屏。心跳机制时长是VX1 lcd内部规定，主机控制器无法更改。
需要优化userdebug版本开机时长，其中在aboot阶段花费时间较长，需要做系统优化。
PS: user版本开机正常，因为user版本开机时间短

userdebug版本不是交付版本，优先级降低暂不处理。
