Junjie Mao ffe213359c board_inspector/extractors: extract cache topology and capabilities
This patch extracts information on cache topology and capabilities and put
them under the `/acrn-config/caches` node in the board XML in the following
manner.

  <caches>
    <cache level="1" id="0x0" type="1">
      <cache_size>32768</cache_size>
      <line_size>64</line_size>
      <ways>8</ways>
      <sets>64</sets>
      <partitions>1</partitions>
      <self_initializing>1</self_initializing>
      <fully_associative>0</fully_associative>
      <write_back_invalidate>0</write_back_invalidate>
      <cache_inclusiveness>0</cache_inclusiveness>
      <complex_cache_indexing>0</complex_cache_indexing>
      <processors>
        <processor>0x0</processor>
        <processor>0x1</processor>
      </processors>
    </cache>
    <cache level="1" id="0x0" type="2"> ... </cache>
    <cache level="1" id="0x1" type="1"> ... </cache>
    <cache level="1" id="0x1" type="2"> ... </cache>
    ...
    <cache level="2" id="0x0" type="3"> ... </cache>
    <cache level="2" id="0x1" type="3"> ... </cache>
    ...
    <cache level="3" id="0x0" type="3"> ... </cache>
  </caches>

Each cache block is represented by a separate `cache` node identified by
its level, cache ID and type (as reported by CPUID). More information, such
as the size, characteristics and capabilities, are attached as children of
the node.

The current implementation fetches cache information solely from the CPUID
leaf 4H. In the future more cache-related information, such as those in the
ACPI RTCT tables, will be appended here.
