spi: imx: pass struct spi_transfer to prepare_transfer()
In an upcoming patch, mx51_ecspi_prepare_transfer() needs access to the
word_delay parameter. To enable controller-specific handling of such
per-transfer parameters, extend the prepare_transfer() function of the
spi_imx_devtype_data interface to take a struct spi_transfer argument,
update all controller-specific implementations accordingly.
