docs: misc-devices/pci-endpoint-test.txt: convert to ReST

- Use titles markups;
- Adjust identation;
- use literal markup;
- Use the proper notation for footnotes.

+Driver for PCI Endpoint Test Function
+=====================================
+
+This driver should be used as a host side driver if the root complex is
+connected to a configurable PCI endpoint running ``pci_epf_test`` function
+driver configured according to [1]_.
+
+The "pci_endpoint_test" driver can be used to perform the following tests.
+
+The PCI driver for the test device performs the following tests:
+
+	#) verifying addresses programmed in BAR
+	#) raise legacy IRQ
+	#) raise MSI IRQ
+	#) raise MSI-X IRQ
+	#) read data
+	#) write data
+	#) copy data
+
+This misc driver creates /dev/pci-endpoint-test.<num> for every
+``pci_epf_test`` function connected to the root complex and "ioctls"
+should be used to perform the above tests.
