This patch is to support direct assignment of P2SB bridge to one pre-launched
VM for EHL. User can configure this per-VM attribute in scenario xml:
<mmio_resources desc="MMIO resources.">
<p2sb>y</p2sb>
</mmio_resources>
Set p2sb to y to passthru P2SB bridge to VM, and n otherwise.

Virtual interrupts injection and memory mapping operations can impact
target VM. By design, these type of operations from lower severity VM
to higher severity VM should be blocked by the hypervisor.
While the hypercalls are the interface between SOS VM and the
hypervisor, severity checks can be implemented at the beginning of
hypercalls needed.
Added severity checks in below hypercalls:
* hcall_set_vm_memory_regions()
* hcall_notify_ioreq_finish()
* hcall_set_irqline()
* hcall_inject_msi()
* hcall_write_protect_page()

New board, EHL CRB, does not have legacy port IO UART. Even the PCI UART
are not work due to BIOS's bug workaround(the BARs on LPSS PCI are reset
after BIOS hand over control to OS). For ACRN console usage, expose the
debug UART via ACPI PnP device (access by MMIO) and add support in
hypervisor debug code.
Another special thing is that register width of UART of EHL CRB is
1byte. Introduce reg_width for each struct console_uart.

This patch is to support the Inter-VM communication by IVSHMEM
in config tool.
Users can configure IVSHMEM_ENABLE to enable or disable Inter-VM
communication by IVSHMEM; users can configure the name, size,
communication VM IDs of the IVSHMEM devices in the VM settings of
scenario xmls, then config tool will generate the related IVSHMEM
configurations for Inter-VM communication.
The config tool will do sanity check including when saving the xmls:
the format of shared memory region configuration is
[name],[size],[VM ID]:[VM ID](:[VM ID]...);
the max size of the name is 32 bytes;
the names should not be duplicated;
the mininum value of shared memory region size is 2M;
the value of shared memory region is a power of 2;
the size of share memory region should not extended the size of
