Binbin Wu 21aa1907fd hv: vcpuid: cpuid leaf 07h has subleaf
Two changes:

1. cpuid leaf 07h has subleaf:
According to SDM 3-194 Vol.2A, Table 3-8, cpuid leaf 07h has sub-leaves.
cpuid.07.eax reports the maximum input for sub-leaves.
Since there is no definition for subleaf > 0 in SDM, hv only supports subleaf 0.

2. In currently hv code, cpuid leaf function 14h is disabled,
CPUID.07H:EBX.INTEL_PROCESSOR_TRACE should be disabled as well.

Usage is:
```

   .. code-block:: c

      a=b=c=0;
```
or, for example:
