[PATCH v1 03/12] app/mldev: add test case to validate device ops

[Srikanth Yalavarthi <syalavarthi@marvell.com>]

Added test case to validate device handling operations. Device ops
test is a collection of multiple sub-tests. Enabled sub-test to
validate device reconfiguration. Set device_ops as the default test.
