x86/ioreq: Provide out-of-line wrapper for the handle_mmio()
The IOREQ is about to be common feature and Arm will have its own
implementation.
But the name of the function is pretty generic and can be confusing
on Arm (we already have a try_handle_mmio()).
In order not to rename the function (which is used for a varying
set of purposes on x86) globally and get non-confusing variant on Arm
provide a wrapper ioreq_complete_mmio() to be used on common and Arm code.
