lib: devres: Simplify API devm_iounmap() implementation
Simplify devm_iounmap() implementation by dedicated API devres_release()
compared with current solution, namely, devres_destroy() + iounmap()
devres_release() has the following advantages:
- it is simpler if devm_iounmap()'s parameter @addr is valid, namely
@addr was ever returned by one of devm_ioremap() variants.
- it can avoid unnecessary iounmap(@addr) if @addr is not valid.
