Use resource_size() for {request/release}_mem_region and ioremap.

Applied to ide-next-2.6, thanks.

 
-	ahwif->regbase = (u32)ioremap(res->start, res->end - res->start + 1);
+	ahwif->regbase = (u32)ioremap(res->start, resource_size(res));
 	if (ahwif->regbase == 0) {
 		ret = -ENOMEM;
 		goto out;

That needs some fixing.  ioremap()'s return value is an
"__iomem" pointer, not an integer.  ->regbase's type should be
changed to something like "void __iomem *" etc.
