The STM32 DMA3 is a Direct Memory Access controller with different features
depending on its hardware configuration.
The channels have not the same capabilities, some have a larger FIFO, so
their performance is higher.

STM32 DMA3 controller is able to suspend an ongoing transfer (the transfer
is suspended after the ongoing burst is flushed to the destination) and
resume it from the point it was suspended. No need to reconfigure any
register.

Implement own device_tx_status ops to compute the residue with a finer

STM32 DMA3 driver supports the 3 hardware configurations of the STM32 DMA3
controller:
- LPDMA (Low Power): 4 channels, no FIFO

The High Performance Direct Memory Access (HPDMA) controller is used to
perform programmable data transfers between memory-mapped peripherals
and memories (or between memories) via linked-lists.
There are 3 instances of HPDMA on stm32mp251, using stm32-dma3 driver, with
16 channels per instance an
On STM32 DMA3, channels can be reserved, so they are non available for
Linux. This non-availability creates a mismatch between dma_chan id and
DMA3 channel id.
Use dma_async_device_channel_register() to register the channels
after controller registration and change the default channel name, so tha
Channel device name is used for sysfs, but also by dmatest filter function.
With dynamic channel registration, channels can be registered after dma
controller registration. Users may want to have specific channel names.
If name is NULL, the channel name relies on previous implementation,
dmachan.
