nios2: Fix ioremap
Commit 5ace77e0b41a ("nios2: remove __ioremap") removed the following code,
with the argument that cacheflag is always 0 and the expression would
therefore always be false.
if (IS_MAPPABLE_UNCACHEABLE(phys_addr) &&
IS_MAPPABLE_UNCACHEABLE(last_addr) &&
!(cacheflag & _PAGE_CACHED))
return (void __iomem *)(CONFIG_NIOS2_IO_REGION_BASE + phys_addr);
This did not take the "!" in the expression into account. Result is that
nios2 images no longer boot. Restoring the removed code fixes the problem.
