[dts] [PATCH] vm_pw_mgmt_policy: fixes core mask and driver

[Tu, Lijuan]

> 1. Now vm_power_manager only grants access to the cores listed
>    in its coremask, so change core number to be the one
>    from vm_power_mgr core mask.
> 2. Replaced driver igb_uio to vfio-pci
> 3. Resetsynchronize system clock after the test completion.
