net/cadence_gem: Implement SAR match bit in rx desc
Bit 27 of the RX buffer desc word 1 should be set when the packet was
accepted due to specific address register match. Implement.
This feature is absent from the Xilinx documentation (UG585) but the
behaviour is tested as accurate on real hardware.

net/cadence_gem: Prefetch rx descriptors ASAP
The real hardware prefetches rx buffer descriptors ASAP and
potentially throws relevant interrupts following the fetch
even in the absence of a received packet.

net/cadence_gem: simplify rx buf descriptor walking
There was a replication of the rx descriptor address walking logic.
Reorder the flow control to remove. This refactoring also obsoletes
the local variables packet_desc_addr and last_desc_addr.
