[src/trunk]: src/sys/arch convert to newer HYPERVISOR_physdev_op() interface,...

[jdolecek <jdolecek%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/05d9a785581e
branches:  trunk
changeset: 971330:05d9a785581e
user:      jdolecek <jdolecek%NetBSD.org@localhost>
date:      Tue Apr 21 20:13:39 2020 +0000

description:
convert to newer HYPERVISOR_physdev_op() interface, now command and the
arg are separate arguments - this is needed for newer physdev_op commands

remove code for PHYSDEVOP_IRQ_UNMASK_NOTIFY, it is obsolete since
interface version 0x00030202 and is unsupported by newer versions of Xen

confirmed working on amd64 Dom0, i386 compile-tested only
