Merge series "Use clocks property in a device node" from Sameer Pujar <spujar@nvidia.com>:

Browse Source 
It is recommended to not specifiy clocks property in an endpoint subnode.
This series moves clocks to device node.

However after moving the clocks to device node, the audio playback or
capture fails. The specified clock is not actually getting enabled and
hence the failure is seen. There seems to be a bug in simple-card-utils.c
where clock handle is not assigned when parsing clocks from device node.

Fix the same and revert original change which actually added clocks
property in endpoint subnode. Also update Jetson AGX Xavier DT where the
usage is found.
