Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3.
With the new bindings boards can customize and tweak the DMA channel
priority to match their needs. With the new binding the memcpy is safe
to be used since with the old binding it was not possible for a driver
to know which channel is allowed to be used as non HW triggered channel.
Using the new binding will allow us to reserve PaRAM slots to be used by
the DSP which was not possible before and prevented the da850 boards to be
moved to DT only.
Note that the DMA memcpy is disabled, it can be enabled by reserving
channels for memcpy by adding the following property to the edma node:
ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */

It was found that when a process was rapidly sending MADs other processes could
be hung in their unregister calls.
This would happen when process A was injecting packets fast enough that the
single threaded workqueue was never exiting ib_mad_completion_handler.
Therefore when process B called flush_workqueue via the unregister call it
would hang until process A stopped sending MADs.
The fix is to periodically reschedule ib_mad_completion_handler after
processing a large number of completions. The number of completions chosen was
decided based on the defaults for the recv queue size. However, it was kept
fixed such that increasing those queue sizes would not adversely affect
fairness in the future.

* WQE are supported on the send queue

The cross-channel feature allows to execute WQEs that involve
synchronization of I/O operations’ on different QPs.
This capability enables to program complex flows with a single
function call, hereby significantly reducing overhead associated
with I/O processing.
Cross-channel operations support is indicated by HCA capability
information.
The queue pairs can be configured to work as a “sync master queue”
or “sync slave queues”.
The added flags are:
1. Device capability flag IB_DEVICE_CROSS_CHANNEL for the
devices that can perform cross-channel operations.
2. CQ property flag IB_CQ_FLAGS_IGNORE_OVERRUN to disable CQ overrun
check. This check is useless in cross-channel scenario.
3. QP property flags to indicate if queues are slave or master:
* IB_QP_CREATE_MANAGED_SEND indicates that posted send work requests
will not be executed immediately and requires enabling.
* IB_QP_CREATE_MANAGED_RECV indicates that posted receive work
requests will not be executed immediately and requires enabling.
* IB_QP_CREATE_CROSS_CHANNEL declares the QP to work in cross-channel
mode. If IB_QP_CREATE_MANAGED_SEND and IB_QP_CREATE_MANAGED_RECV are
not provided, this QP will be sync master queue, else it will be sync
slave.
