[Feature] adc设备驱动优化

[illustriousness]

Describe problem solved by the proposed feature

现在的adc驱动无法使用 常见的adc+dma方式读取数据 是否可以考虑用类似如下的结构体来支持多通道采样呢

struct adc_sequence {
    uint32_t channels;         /* 通道掩码，可同时启用多个通道 */
    int16_t *buffer;           /* 存储转换结果的缓冲区 */
    uint32_t buffer_size;      /* 缓冲区大小 */
    uint8_t resolution;        /* 分辨率 */
    uint8_t oversampling;
};
