[VirtLayer] Changes to the interrupt handling in POK

I don't know how to handle that in x86. You should run the POK handler in
supervisor mode and then decrease the permission level, when you run the
RTEMS handler, to guarantee segregation. You may have to change the
interrupt so that instead of calling the RTEMS handler, it returns into it.
This will depend on the x86 interrupt model that I don't know (mainly on
how you change processor state and how you return from interrupt). Maybe
Dr.Joel or Julian can help you with that.
