devres: remove devm_request_and_ioremap()
devm_request_and_ioremap() was obsoleted by the commit 7509657 ("lib: devres: Introduce devm_ioremap_resource()") and has been deprecated for a long time. So, let's remove this function. In addition, all usages of devm_request_and_ioremap() are also removed. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
