net: ravb: Allocate correct number of queues based on SoC support

Use the per-SoC match data flag `nc_queues` to decide how many TX/RX
queues to allocate. If the SoC does not provide a network-control queue,
fall back to a single TX/RX queue. Obtain the match data before calling
alloc_etherdev_mqs() so the allocation is sized correctly.
