Update the Hyper-V vPCI driver to use the Server-2016 version of the vPCI
protocol, fixing MSI creation and retargeting issues.
Changes since v1:
- reduced spew in protocol negotiation (Dan Carpenter)
- work-around work racing Hyper-V patch (Stephen Hemminger)
- formatting
From: Jork Loeser
To ease parallel effort to centralize CPU-number-to-vCPU-number
conversion, temporarily stand up own version, file-local
hv_tmp_cpu_nr_to_vp_nr(). Once the changes have merged, this
work-around can be removed, and the calls replaced with
hv_cpu_number_to_vp_number().

The hv_pcibus_device structure contains an in-memory hypercall argument
that must not cross a page boundary. Allocate the structure as a page
to ensure that.
