docs: remove no longer existent limitation of spi slave

If the length of the transmission is greater than the buffer length, only the initial number of bits specified in the :cpp:member:`length` member will be sent and received. In this case, :cpp:member:`trans_len` is set to :cpp:member:`length` instead of the actual transaction length. To meet the actual transaction length requirements, set :cpp:member:`length` to a value greater than the maximum :cpp:member:`trans_len` expected. If the transmission length is shorter than the buffer length, only the data equal to the length of the buffer will be transmitted.

- The ESP32 DMA hardware has a limit to the number of bytes sent by a Host and received by a Device. The transaction length must be longer than 8 bytes and a multiple of 4 bytes; otherwise, the SPI hardware might fail to receive the last 1 to 7 bytes.
