Angelo Dureghello 5223c9c1cb spi: spi-fsl-dspi: fix broken DSPI_EOQ_MODE ...

This patch fixes the dspi_eoq_write function used by the
ColdFire mcf5441x family. The 16 bit cmd part must be re-set at
each data transfer.

Also, now that fifo_size variables are used for eoq_read/write,
a proper fifo size must be set (16 slots for the ColdFire dspi
module version).
