[PATCH] iio: adc: rockchip_saradc: Make use of the helper function devm_platform_ioremap_resource()

From: Cai Huoqing <hidden>
Date: 2021-09-08 10:56:50 

Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately

Applied to the togreg branch of iio.git and pushed out as testing for 0-day to
see if it can find anything we missed.

Thanks,
