Joy Zou c91c8d3830 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)
[ 66.278785] dmatest: dma0chan0-copy0: summary 1 tests, 1 failures 0.32 iops 4 KB/s (0)
