Subject: [PATCH] staging: media: imx: Use devm_platform_ioremap_resource().

This patch fixes a warning by coccicheck:
drivers/staging/media/imx/imx7-mipi-csis.c:973:1-12: WARNING: Use devm_platform_ioremap_resource for state -> regs

Use devm_platform_ioremap_resource helper which wraps platform_get_resource()
and devm_ioremap_resource() together.
