accel/habanalabs: expose module id through sysfs
Module ID exposes the physical location of the device in the server,
from the pov of the devices in regard to how they are connected by
internal fabric.
This information is already exposed in our INFO ioctl, but there are
utilities and scripts running in data-center which are already
accessing sysfs for topology information and it is easier for them
to continue getting that information from sysfs instead of opening
a file descriptor.
