Unlike other CPU IDs, the cpu_id field under //processors//thread in the
board XML is in decimal as it is assigned by the kernel continuously,
starting from 0. However, the cache info extractor today parses them as
hexadecimal numbers, leading to incomplete cache info when more than 10
processors are present on the board. This patch fixes this issue.

Today ACRN works only on platforms with a single PCI domain (which is true
for most client and IoT platforms). This limitation is also used to
simplify the implementation of the board inspector. As a result, on
platforms with multiple PCI domains, the board inspector may crash when
parsing information about PCI devices.
This patch adds a check on the number of PCI domains before the board
inspector attempts to extract any information, and terminates the tool
early if multiple PCI domains are detected.

According to DX recommendations, this patch adds a Boolean item to each
vCPU which allows users to specify the vCPUs intended for
real-time-critical tasks. This information will be used to organize other
widgets (CAT-related ones for now) in the configurator to tell apart
real-time ones from the others for better clarity.
All vCPUs are by default not real-time-critical, except those in the RT VMs

Different from other nodes which have static default values, the virtual
BDF nodes of virtual UART endpoints or IVSHMEM interfaces have a set of
default values and should be used with uniqueness guaranteed. The existing
default value mechanism in XSD does not include support for this.
This patch adds two more ACRN-specific annotations, namely `acrn:defaults`
and `acrn:unique-among`, that have the following semantics.
- `acrn:defaults` is a Python expression that evaluates to an iterable.
- `acrn:unique-among` is an xpath that specifies the nodes. Each node
within the select ones shall have a value unique among them. The xpath
is evaluated with the variable `parent` defined as the parent node
under which the vBDF node is to be appended.

Page table entry present check is page table type

Using the SSRAM area size extracted by config_tools, the patch changes
the hard-coded GPA SSRAM area size to its actual size, so that
pre-launched VMs can support large(>8MB) SSRAM area.
When booting service VM, the SSRAM area has to be removed from Service
VM's mem space, because they are passed-through to the pre-rt VM. The
code was bugged since it was using the SSRAM area's GPA in the pre-rt
VM. Changed it to GPA in Service VM.

The GPA SSRAM area size in pre-launched VMs was hard-coded to 8MB.
Since this area is mapped from host SSRAM area, it will cause compile
problem when host's SSRAM area is larger than 8MB.
To solve this issue, we have to calculate SSRAM area's size in
gpa.py, and generate a macro PRE_RTVM_SW_SRAM_MAX_SIZE for HV
to use.
PRE_RTVM_SW_SRAM_START_GPA/END_GPA can be calculated by end/size
in HV, so they are removed.
When SSRAM is not configured in the system, PRE_RTVM_SW_SRAM_MAX_SIZE
is set to 0.
Crl_bin is not needed in guest. So it's size is removed in bin_gen.py.
