dpaa2-eth: add debugfs statistics
Export detailed driver counters through debugfs.
Statistics already available in ethtool are presented in a
structured manner. Includes per-core, per-FQ and per-channel statistics.
Also transition from module_fsl_mc_driver to explicit module_init/exit
in order to create the debugfs directory besides registering the driver.
