As there is a requirement for conmunication between VMs on uart port,
but for Pre-launched VM, the only way is to create vuart for each VM and
connect them at hypervisor side. So, the vuart code should be moved from
/debug to /dm so that they can also be used in release version.
For the console related code, as no need to support in release version,
so leave them at debug directory.

In previous code, only for pre-launched VM, hypervisor would create
vuart console for each VM. But for post-launched VM, no vuart is
created.
In this patch, create vuart according to configuration in structure
acrn_vm_config. As the new configuration is set for pre-launched VM and
post-launched VM, and the vuart initialize process is common for each
VM, so, remove CONFIG_PARTITION_MODE from vuart related code.

When shutting down SOS VM, the shared sbuf is released from guest OS, but
the per cpu sbuf pointers in hypervisor keep inact. This creates a problem
that after SOS is re-launched, hypervisor could write to the shared
buffer that no longer exists.
This patch implements sbuf_reset() and call it from reset_vcpu() to
reset sbuf pointers.

vuart it used for SOS to output log to HV console,
so if dbg uart is disabled, it need be disabled too:
just unregister its PIO.

This patch fixes incorrect vm_id captured when sampling PMU data. Currently,
the vm_id gets attributed to ACRN hypervisor, rather than actual guest vm_id.
The issue is identified that the existing code captures the guest vm info
after vmexit_hander function is completed, in which the profiling module
points its context to VMM. When the vmexit happens by PMI, the guest context
should be captured so that the attribution to proper guest vm can happen.
This change will also allow to capture more accurate TSC when vmexit happens.

serial PCI device is just used for HV/SOS output debug information;
because it is used in hypervisor layer, SOS should not touch it.
so need to check and hide it from SOS.
