MLK-14528: ASoC: sdma: Update period/segment max bytes (part 1)
Commit 665ced16cf044 ("MLK-10050 dma: imx-sdma: add support for sdma
memory copy") enforces maximum SDMA buffer descriptor length at 65532,
but doesn't update period_bytes_max or max_segment size in DMA drivers.
Thus, resulting in the following bug:
$ arecord -Dhw:0,0 -r 192000 -f S20_3LE -c 1 -d 10 audio192k20b1c.wav
imx-sdma: SDMA channel 5: maximum period size exceeded: 65534 > 65532
