mlx4_en: Added self diagnostics test implementation
The selftest includes 5 features:
1. Interrupt test: Executing commands and receiving command completion
on all our interrupt vectors.
2. Link test: Verifying we are connected to valid link partner.
3. Speed test: Check that we negotiated link speed correctly.
4. Registers test: Activate HW health check command.
5. Loopback test: Send a packet on loopback interface and catch it on RX side.
