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

[Andrea Parri <parri.andrea@gmail.com>]

Michael reported that the x86/hyperv initialization code printed 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";
with this addition, the dmesg read:

  [    0.000138] Booting paravirtualized kernel on Hyper-V
