pci_endpoint_test: Add 2 ioctl commands
Add MSI-X support and update driver documentation accordingly.
Add 2 new IOCTL commands:
- Allow to reconfigure driver IRQ type in runtime.
- Allow to retrieve current driver IRQ type configured.
Add IRQ type validation before executing the READ/WRITE/COPY tests.
