spi: mpc8xx: Fix transfert when input or output buffer is NULL xfer ops can be passed a NULL input or output buffer. At the time being the driver ignores it and overwrites memory at 0. Define a dummy buffer and use it when either input or output buffer is NULL. Bail out when both are NULL as it shouldn't. Also increase MAX_BUFFER len to 32k as the current is pretty low.
