When a TDX guest runs on Hyper-V, the hv_netvsc driver's netvsc_init_buf()
allocates buffers using vzalloc(), and needs to share the buffers with the
host OS by calling set_memory_decrypted(), which is not working for
vmalloc() yet. Add the support by handling the pages one by one.

The vmbus driver uses ACPI for interrupt assignment on

Update the vmbus driver to discover interrupt configuration

This change removes dependency on ACPI when buidling the hv drivers to
allow Virtual Trust Level boot with DeviceTree.
