[Impact]
Since linux-azure can also be used for local Hyper-V guests on
Windows 10 Pro running on arm64 platforms, enable arm64 build
for this kernel as well.
[Test Case]
Microsoft tested.
Boot an arm64 VM on a machine running Win10Pro with Hyper-V.
[Where things could go wrong]
Some of the patches touch common PCI code. Device detection could be
impacted.
