Mark switch cases where we are expecting to fall through.
This patch fixes the following warning (Building: arm):
drivers/dma/imx-dma.c: In function ‘imxdma_xfer_desc’:
drivers/dma/imx-dma.c:542:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (slot == IMX_DMA_2D_SLOT_A) {
^
drivers/dma/imx-dma.c:559:2: note: here
case IMXDMA_DESC_MEMCPY:
^~~~
Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.
