There are multiple types of resets that need to be handled
by the mei device.
The reset may be initiated from both sides host or fw.
The host requests reset on probe and remove,
power state transaction, and errors,
while ME FW may request reset upon error.
If the native device undergo reset the host application
has to be notified.

The virtio_mei declares host buffer of size 128 slots, each

For synchronization hw_ready and host_reset configuration flags
are used that emulates mei reset flow.

In the current implementation sigev_notify is configured as
SIGEV_THREAD. When wdt expires an async thread is created and
the registered timer callback is called in the context of this
thread, then the watchdog interrupt emulation would require the
thread to assert intr on this pci dev.
There would be a race condition that when the wdt pci device is
freed in pci device deinit and then a timer expires. In this case
the wdt expired thread will access a freed buffer which would cause
problem such as heap corruption and segment fault.
In this patch we replace timer API with acrn_timer which is based
on timerfd/epoll mechanism to avoid the race condition.
