Default ioremap is ioremap_nocache, so devm_ioremap has the same function with devm_ioremap_nocache, which can just be killed to save the size of devres.o This patch is to use use devm_ioremap instead of devm_ioremap_nocache, which should not have any function change but prepare for killing devm_ioremap_nocache.
