[PATCH -next] ARM: zx: Use devm_platform_ioremap_resource()

From: Wang ShaoBo
Date: Fri Sep 18 2020 - 04:05:39 EST


Make use of devm_platform_ioremap_resource() provided by driver
core platform instead of duplicated analogue. dev_err() is
removed because it has been done in devm_ioremap_resource().
