 挂载fatfs

 @int fatfs模式,可选fatfs.SPI,fatfs.SDIO,fatfs.RAM,fatfs.USB
 @string fatfs挂载点, 通常填""或者"SD", 底层会映射到vfs的 /sd 路径
 @int 传入spi device指针,或者spi的id,或者sdio的id
 @int 片选脚的GPIO 号, spi模式有效,若前一个参数传的是spi device,这个参数就不需要传
 @int SPI最高速度,默认10M, 若前2个参数传的是spi device,这个参数就不需要传
+@int TF卡电源控制脚,TF卡初始前先拉低复位再拉高,如果没有,或者是内置电源控制方式,这个参数就不需要传
+@int TF卡电源复位过程时间,单位ms,默认值是1
 @return bool 成功返回true, 否则返回nil或者false
 @return string 失败的原因
