spi/imx: make spi_imx_data.devtype_data member point to const data
This prepares *of_device_id.data becoming const. Without this change the following warning would occur: drivers/spi/spi-imx.c: In function spi_imx_probe: drivers/spi/spi-imx.c:814:24: warning: assignment discards const qualifier from pointer target type [enabled by default] Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
