[spi]添加rt_spi_bus_attach_device_cspin 函数 (#6916)

2023-02-12T03:14:54Z

这个函数实现了原先的挂载功能，并且调用pin框架，初始化cs引脚，是一个功能相对完善的挂载函数。用户也能更简单的使用。该函数取代rt_spi_bus_attach_device，后续rt_spi_bus_attach_device会被逐渐淘汰掉。新的BSP以及软件包应当使用rt_spi_bus_attach_device_cspin新函数。 STM32L475潘多拉测试通过。

rt_device_write/read return data type as rt_ssize_t

2023-02-08T02:43:57Z

rt_ssize_t can give negative error code, which follows the unix style correctly
