The current struct vcpu has two members, namely 'struct vhm_request req' and 'struct mem_io mmio', that hold similar info, including the address, direction, size, value and status of mmio reqeusts. As a step towards a unified framework for both MMIO/PIO, this patch unifies these two members by a tailored version of vhm_reqeust, mostly with the reserved fields dropped. The definitions to request types, directions and process status are reused. Handling errors during emulations will be revisited after the I/O emulation paths are unified. Thus for this patch the mmio.mmio_status in inherited by io_req.processed which is not yet properly processed.
