hsi: controllers:remove redundant code
Use devm_ioremap_resource() in order to make the code simpler, and remove redundant return value check of platform_get_resource() because this value is alreadytaken care by devm_ioremap_resource() Signed-off-by: Sanjeev Sharma <sanjeev_sharma@mentor.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
