UOS requires an wakeup reason when resumed from S3 suspend. If user
use "acrnctl resume [VMNAME]" without an reason, 0x0 will be used
as default reason, and this is not work. We can use CBC_WK_RSN_BTN
instead.

- move the functions to access physical PCI configuration space from
pci_pt.c to the new file dm/hw/pci.c, so they can be accessed in
sharing mode as well. The new folder dm/hw is created in order to
move APIs talking to physical PCI devices out of dm/vpci.
- move the common vpci code from header file pci_priv.h to core.c.
- move file include/dm/vpci/vpci.h one level up. It seems the folder
include/dm/vpci is not necessary.
- This patch only moves code around, and doesn't make any logical
changes. Besides removes the static keyword from pci_pdev_read_cfg()
and pci_pdev_write_cfg()

In vmei_start() the HBM host client is created,
it handles HBM protocol.
The HBM client is a management object and
is not exposed by the mei native driver.
The communication between TX and RX threads
is handed via internal pipe(2).
Second, we connect all fixed address clients as the mei
protocol doesn't provide connection mechanism for them,
they appear always connected.
Last, the hw_ready is set.
Define virtio_mei_ops, ass all the handlers are now available.

The reset may be initiated from both sides host or fw.
The host requests reset on probe and remove,

TX have two segment buffers one for header and one for data.
The virtio_mei declares host buffer of size 128 slots, each

devicemodel/include/vmcfg_config.h, which contains many macro symbols
for conditionally compiling. This feature is disabled by default, to
enable it, You can switch to devicemodel/vmcfg/ and run 'make' with
these options:
'make menuconfig'
run 'make menuconfig' at ./devicemodel/vmcfg/, and configure manually.
When you finished, save your changes to ./devicemode/vmcfg/.config
'make oldconfig'
Overwrite ./devicemodel/vmcfg/.config with your config file, then run
'make oldconfig' at ./devicemodel/vmcfg
