ACRN interepts vm_set/reset_ptdev_intx_info hypercalls to set
the SOS vdev properties to indicate it is assigned to UOS. Today,
upon vm_reset_ptdev_intx_info hypercall ACRN does not revert the SOS
vdev properties back to that of SOS, as vbdf and pbdf were not
part of the API. This would leave ACRN data structures in an incorrect
state

Currently VHM driver is opened by using the device file of /dev/acrn_vhm.
But for the upstream purpose it is renamed to /dev/acrn_hsm.
So we need to check that the device file is acrn_vhm or acrn_hsm and then
open the VHM driver.

This patch is for "interrupt storm mitigation", used to reduce
the effect on SOS if an "interrupt storm" happens in UOS.
Add a monitor thread to get UOS pass-through devices interrupt
freqency data; currently, if "interrupt storm" happens, it'll
send a command to delay interrupt injection to UOS for some time.
The parameters: interrupt storm threshold and delay time can be
adjusted according differt HW configure and use case.
