[PATCH 2/5] conf: showing cache/memoryBW monitor features in capabilities

[Wang Huaqiang <huaqiang.wang@xxxxxxxxx>]

From: Huaqiang <huaqiang.wang@xxxxxxxxx>

We learned that the hardware features of CAT, CMT, MBA and MBM
are orthogonal ones, if CAT or MBA is not supported in system,
but CMT or MBM are supported, then the cache monitor or
memoryBW monitor features may not be correctly displayed in
host capabilities through command 'virsh capabilites'.

Showing the cache/memoryBW monitor capabilities even there is
no support of cache allocation or memoryBW allocation features.
