spi: spi-imx: remove unused struct spi_imx_devtype_data::disable_dma callback

In commit 7a908832ace7 ("spi: imx: add fallback feature") the last
user of the struct spi_imx_devtype_data::disable_dma callback was
removed. However the disable_dma member of struct spi_imx_devtype_data
and the callback itself was not removed.

Remove struct spi_imx_devtype_data::disable_dma and mx51_disable_dma()
as they are unused.
