net: thunderx: Optimize RBDR descriptor handling Receive buffer's physical address or iova will anyway not go beyond 49bits, since it is the max supported HW address. As per perf, updating bitfields i.e buf_addr:42 in RBDR descriptor entry consumes lots of cpu cycles, hence changed it to a 64bit field with alignment requirements taken care of.
