cpu-common: use atomic access for interrupt_request

Writes to interrupt_request used non-atomic accesses, but there are a
few cases where the access was not protected by the BQL.  Now that
there is a full set of helpers, it's easier to guarantee that
interrupt_request accesses are fully atomic, so just drop the
requirement instead of fixing them.
