[PATCH v2 1/3] Revert "mtd: pxa2xx-flash: switch from ioremap_cache to memremap"

This reverts commit 06968a54790d9dd87a5bb68e8197b5094eff63c3, since NOR
with memory semantics in array mode and RAM are not necessarily the same
thing, and architectures may implement ioremap_cache() and memremap()
with different memory attributes.
