The current binding document only describes a single interrupt. Update the
document by adding the 2 other interrupts.
The driver currently only uses a single interrupt. The HW is however able
to using IRQ grouping to split TX and RX onto separate GIC irqs.

Subject: [PATCH 71/78] net: mediatek: fix TX locking
Inside the TX path there is a lock inside the tx_map function. This is
however too late. The patch moves the lock to the start of the xmit
function right before the free count check of the DMA ring happens.
If we do not do this, the code becomes racy leading to TX stalls and
dropped packets. This happens as there are 2 netdevs running on the
same physical DMA ring.

Subject: [PATCH 72/78] net: mediatek: move the pending_work struct to the
device generic struct
The worker always touches both netdevs. It is ethernet core and not MAC
specific. We only need one worker, which belongs into the ethernets core struct.

Subject: [PATCH 73/78] net-next: mediatek: add support for IRQ grouping
The ethernet core has 3 IRQs. using the IRQ grouping registers we are able
to separate TX and RX IRQs, which allows us to service them on separate
cores. This patch splits the irq handler into 2 separate functiosn, one for
TX and another for RX. The TX housekeeping is split out of the NAPI handler.
Instead we use a tasklet to handle housekeeping.
