Frederic Barrat 31bfbc00d0 tests/qtest: Add XIVE tests for the powernv10 machine
These XIVE tests include:
- General interrupt IRQ tests that:
  - enable and trigger an interrupt
  - acknowledge the interrupt
  - end of interrupt processing
- Test the Pull Thread Context to Odd Thread Reporting Line
- Test the different cache flush inject and queue sync inject operations
