Merge tag 'v4.9.67' into 4.9-1.0.x-imx-fixes-stable-merge

This is the 4.9.67 stable release

Resolved conflicts:
	arch/arm/boot/dts/imx6sx-sdb.dts
	drivers/dma/imx-sdma.c
	drivers/mmc/core/host.c
	drivers/usb/chipidea/otg.c
	sound/soc/fsl/fsl_ssi.c

This merge also reverts commit 3a654a85932f ("dmaengine:
imx-sdma - correct the dma transfer residue calculation"). The
downstream kernel seems to use different structures and already
use buf_ptail in its calculation.
