The 'iasl' binary (from the acpica) package can be installed in
different locations depending on the distribution. By default,
we look for it under '/usr/sbin/'. But it is also often found
under '/usr/bin'. This can be overwritten by setting the ASL_COMPILER
flag when compiling ACRN.
This patch goes one step further and automatically determine where
'iasl' is on the development system if the ASL_COMPILER variable
has not been set already.

In VT-d scenario, if MSI interrupt has been enabled,
vCPU writes the content in MSI registers,
and all bits of the content are read-only.
In this case, hypervisor code will call
enable_disable_msi(vdev, false), which will disable MSI.
And there's no chance to call remap_vmsi.
This is wrong behavior, which will result in the disable of MSI.

- init_interrupt()
