This patch adds the logic needed to fully parse an SR-IOV extended
capability structure. Such information will later be used to extract all
information about physical and virtual functions.

Many of the license and Intel copyright headers include the "All rights

throughout the code (hypervisor, devicemodel and misc).

This patch extracts information on devices and put them under the
`/acrn-config/devices` node in the board XML.
The generated XML looks like the following:
<devices>
<bus type="system">
<acpi_object>\_SB_</acpi_object>
<bus id="PNP0A08" type="pci" address="0x0" description="...">
<vendor>0x8086</vendor>
<identifier>0x591f</identifier>
<subsystem_vendor>0x1028</subsystem_vendor>
<subsystem_identifier>0x07a1</subsystem_identifier>
<class>0x060000</class>
<acpi_object>\_SB_.PCI0</acpi_object>
<resource type="bus_number" min="0x0" max="0x3e" len="0x3f"/>
<resource type="io_port" min="0x0" max="0xcf7" len="0xcf8"/>
<resource type="io_port" min="0xcf8" max="0xcf8" len="0x8"/>
<resource type="io_port" min="0xd00" max="0xffff" len="0xf300"/>
<resource type="memory" min="0x10000" max="0x1ffff" len="0x0"/>
<resource type="memory" min="0xa0000" max="0xbffff" len="0x20000"/>
<resource type="memory" min="0xc0000" max="0xc3fff" len="0x4000"/>
<resource type="memory" min="0xc4000" max="0xc7fff" len="0x4000"/>
...
<capability id="vendor_specific"/>
<device address="0x1"> ... </device>
...
<bus>
<bus>
<device> ... <device>
<devices>
The hierarchy of devices are based on the hierarchy of device objects in
the ACPI namespace (which is established by interpreting the ACPI DSDT and
SSDT tables). Typically most device objects are under the predefined
`_SB_` (i.e. System Bus) object under which an object representing the PCI
root complex (`\_SB_.PCI0` in the example above) can be found. The PCI
devices attached to bus 0 are listed as children of the PCI root complex
node.
For each bus or device, the board inspector tries best to parse the
information from both ACPI device objects and PCI configuration space to
extract the following:
- the model (via `_HID` object and PCI vendor ID, device ID and class code),
- assigned resources (via `_CRS` object and PCI BARs),
- capabilities (via the PCI capability list)
v1 -> v2:
- Fix references to undeclared modules or variables.
- Make the ACPI extractor advanced and not enabled by default.
- Extract the secondary I/O and memory-mapped I/O addresses of bridges.
