On some platforms the number of bits in the cbm_mask might not be
divisible by 4 (and not even by 2), so we need to properly count the
bits.  Similar file, min_cbm_bits, is properly parsed and used, but if
the number is greater than one, we lose the information about
granularity when reporting the data in capabilities.  For that matter
always report granularity, but if it is not the same as the minimum,
add that information in there as well.

Add cache resource control into capabilities for CAT without CDP:

  <cache>
    <bank id='0' level='3' type='unified' size='15360' unit='KiB' cpus='0-5'>
      <control min='768' unit='KiB' scope='both' max_allocation='4'/>
    </bank>
  </cache>

and with CDP:

  <cache>
    <bank id='0' level='3' type='unified' size='15360' unit='KiB' cpus='0-5'>
      <control min='768' unit='KiB' scope='code' max_allocation='4'/>
      <control min='768' unit='KiB' scope='data' max_allocation='4'/>
    </bank>
  </cache>

Also add new test cases for vircaps2xmltest.

Add info from yet another machine, this time with resctrl data so that
we can extend tests easily in a test-driven way.

We're only adding only info about L3 caches, we can add more
later (just by changing one line), but for now that's more than enough
without overwhelming anyone.

XML snippet of how this should look like (also seen as part of the commit):

  <cache>
    <bank id='0' level='3' type='both' size='8192' unit='KiB' cpus='0-7'/>
  </cache>

Commit a0fdd2f6 added some data from
the system but forgot 3 files for each cache.

Instead of generating all of the capabilities, let's test more of our
code by probing sysfs data.  This test needs quite some mocking for
now, but it paves the road for more future enhancements (hugepages
probing, for example).

Bit more test data, this time with complete info copied, mainly with
cache information, so we can easily add tests for it.

We'll stop generating the data on the fly, but rather test more of our
APIs.

For now only one test is introduced. It's purpose in life
is to check we don't break NUMA host distances XML format.
