Simplify the logic in the Cadence MACB/GEM driver for determining
when to reschedule NAPI processing, and update it to use NAPI for the
TX path as well as the RX path.

Changes since v1: Changed to use separate TX and RX NAPI instances and
poll functions to avoid unnecessary checks of the other ring (TX/RX)
states during polling and to use budget handling for both RX and TX.
Fixed locking to protect against concurrent access to TX ring on
TX transmit and TX poll paths.
