x86/hyperv: Set pv_info.name to "Hyper-V" 

Michael reported that the x86/hyperv initialization code prints the
following dmesg when running in a VM on Hyper-V:

  [    0.000738] Booting paravirtualized kernel on bare hardware

Let the x86/hyperv initialization code set pv_info.name to "Hyper-V" so
dmesg reports correctly:

  [    0.000172] Booting paravirtualized kernel on Hyper-V

[ tglx: Folded build fix provided by Yue ]
