I tested and showed that the default and overrides are correctly passed to  spi.config().  Since I do not have a oscilloscope i cannot say whether the configuration values were acted upon by the busio.SPI, but i did show that the changes to the project were correct.

Remove redundant I2CDevice.read_into method

A new method (readinto) was added a while ago to replace the read_into method. The origin read_into method is now being removed.
