scripts/coccinelle/api: remove devm_request_and_ioremap.cocci

/// Reimplement a call to devm_request_mem_region followed by a call to ioremap

/// or ioremap_nocache by a call to devm_request_and_ioremap.

/// Devm_request_and_ioremap was introduced in

/// 72f8c0bfa0de64c68ee59f40eb9b2683bffffbb0.  It makes the code much more

/// concise.
