serial: imx: Add DMA buffer configuration via DT
In order to optimize serial communication (performance/throughput VS
latency), we may need to tweak DMA period number and size. This adds
DT properties to configure those values before initialising DMA.
The defaults will stay the same as before.
[update documentation and commit message, rebase to current master,
switch back to DT instead of sysfs]
