Adds a shim layer around the mcux dspi driver to adapt it to the Zephyr spi interface. Unlike the existing k64 spi driver, this driver can be used for other Kinetis SoCs that contain the dspi module.

The mcux driver requires that the rx and tx buffers are the same
|
|
length, however the Zephyr spi interface allows them to be different.
|
|
When they are different, the mcux shim driver uses a local buffer. This
|
|
option defines the size of the local buffer.

This option configures what value to send when the tx buffer length is
|
|
less than the rx buffer length.
