Meco Man 8d6e536e88 [spi] optimize the spi transfer speed. 
If the configurations are the same, we don't need to set again.

Meco Man 93968942c2 [device][spi] 修复 rt_spi_sendrecv8/16 收发不同时的问题 
rt_spi_send_then_recv是先发再等待一个独立的消息接收
rt_spi_transfer是收发同时进行
rt_spi_sendrecv8/16应使用rt_spi_transfer而不是rt_spi_send_then_recv

[spi]添加rt_spi_bus_attach_device_cspin 函数 (#6916) 
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。
