Pawel Moll 3c424f3598 ARM: 7304/1: ioremap: fix boundary check when reusing static mapping 
Since commit 576d2f2525 "ARM: add
generic ioremap optimization by reusing static mappings" ioremap()
is trying to reuse existing static mapping when possible.

The condition checking boundaries of the requested and existing
mappings didn't take in-page offset into consideration though,
which lead to obscure and hard to debug problems when requested
mapping crossed end of the static one.
