They are not supposed to be relaxed. If they are, you probably have a
whole lot of busted drivers :-)
They have the same semantics as readl/writel for memory and as inb/outb
for IO space, they just allow to hide the "type" (memory vs. IO) from
most of the driver code.
We probably need to create a set of _relaxed variants.
