net: hibmcge: Add unicast frame filter supported in this module

MAC supports filtering unmatched unicast packets according to
the MAC address table. This patch adds the support for
unicast frame filtering.

To support automatic restoration of MAC entries
after reset, the driver saves a copy of MAC entries in the driver.
