Subject: [PATCH v3 22/27] tools/testing/nvdimm: replace devm_ioremap_nocache with devm_ioremap

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.
