Elliott Mitchell 9f3be3a6ec xen: switch to using core atomics for synchronization
Now that the atomic macros are always genuinely atomic on x86, they can
be used for synchronization with Xen.  A single core VM isn't too
unusual, but actual single core hardware is uncommon.

Replace an open-coding of evtchn_clear_port() with the inline.

Substantially inspired by work done by Julien Grall <julien@xen.org>,
