Subject: [PATCH] net: airoha: Set REG_RX_CPU_IDX() once in
airoha_qdma_fill_rx_queue()
It is not necessary to update REG_RX_CPU_IDX register for each iteration
of the descriptor loop in airoha_qdma_fill_rx_queue routine.
Move REG_RX_CPU_IDX configuration out of the descriptor loop and rely on
the last queue head value updated in the descriptor loop.
