[PATCH] spi/imx: make devtype_data member point to const data

[PATCH] spi/imx: make devtype_data member point to const data

[Uwe Kleine-König]

This is only cosmetic for now. In case that

	http://mid.gmane.org/1335171381-24869-1-git-send-email-u.kleine-koenig@pengutronix.de

will be applied, it fixes a warning

	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]

though.
