Junjie Mao 88f74b5dbb HV: io: unify vhm_request req and mem_io in vcpu
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.
