pci_endpoint_test: Add 2 ioctl commands

Browse Source 
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.
