* Unlocked mmio-accessors, think carefully before using these.

* Certain architectures will die if the same cacheline is concurrently accessed
* by different clients (e.g. on Ivybridge). Access to registers should
* therefore generally be serialised, by either the dev_priv->uncore.lock or
* a more localised lock guarding all access to that bank of registers.
