driver/ldpaa: Add support of WRIOP static data structure

Wire rate IO Processor (WRIOP) provide support of receive and transmit
ethernet frames from the ethernet MAC.  Here Each WRIOP block supports
upto 64 DPMACs.

Create a house keeping data structure to support upto 16 DPMACs and
store external phy related information.
