This reverts commit 0ac97979b6.
Reason for revert: This static configuration for wakeup IRQs is
no longer needed since we have a mechanism for automatic dynamic
configuration of wakeup IRQs based on requests from ChromeOS VM.
BUG=b:228449597
TEST=Boot ManaTEE and verify wakeup from touchpad and other devices.

Add userspace counterpart to host kernel change CL:3571844 to support

In ACPI world multiple GPEs (HW wires signaling arbitrary event)
can be associated with single SCI. Any pending GPE causes SCI
to be fired and appropriate GPE handler dispatched. In order
to pass-through GPE to the guest and take virtualization actions,
host kernel provides mechanism to bind physical GPE with SCI eventfd and
forward that information the the event listener (crosvm or KVM most likely).
Add userspace counterpart to host kernel GPE forwarding module
implemented in CL:3488959.

For MSIX-capable PCI devices, some BAR regions are described using
VFIO_REGION_INFO_CAP_MSIX_MAPPABLE:
The MSIX mappable capability informs that MSIX data of a BAR can be
mmapped which allows direct access to non-MSIX registers which
happened to be within the same system page.
Add support for this capability so that VfioRegion stores the correct
mmaps information.
Also, fix a couple break conditions to avoid breaking out early.

For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

if device bar is mappable, map bar's gpa to hpa in EPT, guest vcpu

vm.add_mmio_memory could help do this, here vfio_pci send
RegisterMmapMemory request through vm_control socket to do this.
