[PATCH] input: Make use of the helper function devm_platform_ioremap_resource()

[cgel . zte]

From: Lv Ruyi <lv.ruyi@xxxxxxxxxx>

Use the devm_platform_ioremap_resource() helper instead of calling
platform_get_resource() and devm_ioremap_resource() separately.Make the
code simpler without functional changes.
