dmaengine: fsl-edma: implement the cleanup path of fsl_edma3_attach_pd()

commit ccfa3131d4a0347988e73638edea5c8281b6d2c7 upstream.

Current implementation of fsl_edma3_attach_pd() does not provide a
cleanup path, resulting in a memory leak. For example,
dev_pm_domain_detach() is not called after dev_pm_domain_attach_by_id(),
and the device link created with the DL_FLAG_STATELESS is not released
explicitly.

Therefore, provide a cleanup function fsl_edma3_detach_pd() and call it
upon failure. Also add a devm_add_action_or_reset() call with this
function after a successful fsl_edma3_attach_pd().

dmaengine: fsl-edma: change the memory access from local into remote mode in i.MX 8QM

[ Upstream commit 8ddad558997002ce67980e30c9e8dfaa696e163b ]

Fix the issue where MEM_TO_MEM fail on i.MX8QM due to the requirement
that both source and destination addresses need pass through the IOMMU.
Typically, peripheral FIFO addresses bypass the IOMMU, necessitating
only one of the source or destination to go through it.

Set "is_remote" to true to ensure both source and destination
addresses pass through the IOMMU.

iMX8 Spec define "Local" and "Remote" bus as below.
Local bus: bypass IOMMU to directly access other peripheral register,
such as FIFO.
Remote bus: go through IOMMU to access system memory.

The test fail log as follow:
[ 66.268506] dmatest: dma0chan0-copy0: result #1: 'test timed out' with src_off=0x100 dst_off=0x80 len=0x3ec0 (0)

dmaengine: fsl-edma: integrate v3 support

Significant alterations have been made to the EDMA v3's register layout.
Now, each channel possesses a separate address space, encapsulating all
channel-related controls and statuses, including IRQs. There are changes
in bit position definitions as well. However, the fundamental control flow
remains analogous to the previous versions.

EDMA v3 was utilized in imx8qm, imx93, and will be in forthcoming chips.

Relocates the tcd into the fsl_dma_chan structure. This adjustment reduces
the need to reference back to fsl_edma_engine, paving the way for EDMA V3
support.

Unified the edma_writel and edma_writew functions for accessing TCD
(Transfer Control Descriptor) registers. A new macro is added that can
automatically detect whether a 32-bit or 16-bit access should be used
based on the structure field definition. This provide better support
64-bit TCD with future v5 version.

The enum edma_version, which defines v1, v2, and v3, is a software concept

chip reference manual. According to the 7ulp reference manual, it should
be edma2. In the future, there will be edma3, edma4, and edma5, which
could cause confusion. To avoid this confusion, remove the edma_version
and instead use drvdata->flags to distinguish the IP difference.
