This patch add support for interleaved transfer which used
for interleaved audio or 2d video data transfer.
for audio situation, we add 'nump' for number of period frames.

This was removed before due to the complete lack of users, but
3218910fd5 ("dmaengine: Add core function and capability check for
DMA_MEMCPY_SG") and 29cf37fa6d ("dmaengine: Add consumer for the new
DMA_MEMCPY_SG API function.") added it back despite still not having
any users whatsoever.

All references to the slave_id field have been removed, so remove the
field as well to prevent new references from creeping in again.
Originally this allowed slave DMA drivers to configure which device
is accessed with the dmaengine_slave_config() call, but this was
inconsistent, as the same information is also passed while requesting
a channel, and never changes in practice.
In modern kernels, the device is always selected when requesting
the channel, so the .slave_id field is no longer useful.

This is the old DMA_SG interface that was removed in commit
c678fa6634 ("dmaengine: remove DMA_SG as it is dead code in kernel"). It
has been renamed to DMA_MEMCPY_SG to better match the MEMSET and MEMSET_SG
naming convention.
It should only be used for mem2mem copies, either main system memory or
CPU-addressable device memory (like video memory on a PCI graphics card).
Bringing back this interface was prompted by the need to use the Xilinx
CDMA device for mem2mem SG transfers.

Remove the #ifdef in the header, as this only saves a few bytes,
but would require ugly #ifdefs in each driver using it.
Simplify the other user while we're at it.

There are a lot of different structures that need to have a "frozen" abi
for the next 5+ years. Add padding to a lot of them in order to be able
to handle any future changes that might be needed due to LTS and
security fixes that might come up.
It's a best guess, based on what has happened in the past from the
5.4.0..5.4.129 release (1 1/2 years). Yes, past changes do not mean
that future changes will also be needed in the same area, but that is a
hint that those areas are both well maintained and looked after, and
there have been previous problems found in them.
Also the list of structures that are being required based on OEM usage
in the android/ symbol lists were consulted as that's a larger list than
what has been changed in the past.
Hopefully we caught everything we need to worry about, only time will
tell...

If the DMA device supports per channel coherency configuration (a channel
can be configured to have coherent or not coherent view) then a single
device (the DMA controller's device) can not be used for dma_api for all
channels as channels can have different coherency.
Introduce custom_dma_mapping flag for the dma_chan and a new helper to get
the device pointer to be used for dma_api for the given channel.
Client drivers should be updated to be able to support per channel
coherency by:
- dma_map_single(chan->device->dev, ptr, size, DMA_TO_DEVICE);
+ struct device *dma_dev = dmaengine_get_dma_device(chan);
+
+ dma_map_single(dma_dev, ptr, size, DMA_TO_DEVICE);

Additional configuration for the DMA event router might be needed for a
channel which can not be done during device_alloc_chan_resources callback
since the router information is not yet present for the drivers.
If there is a need for additional configuration for the channel if DMA
router is in use, then the driver can implement the device_router_config
callback.

New drivers should use dma_request_chan() instead
dma_request_slave_channel()
dma_request_slave_channel() is a simple wrapper for dma_request_chan()
eating up the error code for channel request failure and makes deferred
probing impossible.
Move the dma_request_slave_channel() into the header as inline function,
mark it as deprecated.
