Adds a new section in reference documentation that lists the
requirements from ACRN upon a processor to boot and function
successfully.
This patch is a starting point and can expect to add a lot
more requirements that would be a translation of
hypervisor/arch/x86/cpu_caps.c

For vuart1, if it's mapped to a real native serial port, we must
re-use the native serial port io base and irq number. If no native
serial port is mapped to vuart1, non-exist io base and irq should
be used.
Please note: UOS launch script may need be updated according to
which serial port index is used by vuart1.
Now, we are using ttyS1 of SOS for vuart1 in our release. User may
need to remap vuart to different ttySx by following above rule if
ttyS1 in user platform is used by other devices like Bluetooth/Wifi.

We should use INIT signal to notify the vcpu threads when
powering off the hard RTVM. To achive this, we should set
the vcpu->thread_obj.notify_mode as SCHED_NOTIFY_INIT.
Patch (27163df9 hv: sched: add sleep/wake for thread object)
tries to set the notify_mode according `is_lapic_pt_enabled(vcpu)`
in function prepare_vcpu. But at this point, the is_lapic_pt_enabled(vcpu)
will always return false. Consequently, it will set notify_mode
as SCHED_NOTIFY_IPI. Then leads to the failure of powering off
hard RTVM.
This patch fixes it by:
- Initialize the notify_mode as SCHED_NOTIFY_IPI in prepare_vcpu.
- Set the notify_mode as SCHED_NOTIFY_INIT after passthroughing lapic to guest.
