Add testfile for lan743x network driver.
Testfile includes the verification of status of autonegotiation.
Ksft modules and ethtool are used for the testing.
net/lib libraries are included for testing.
Add the __init__.py file.
Include /microchip/lan743x as a target in Makefile.
Updated MAINTAINERS list.
