The driver currently subscribes for a late system sleep call.
The initcall_debug log shows that suspend call for ADX device
happens after the parent device (AHUB). This seems to cause
suspend failure on Jetson TX2 platform. Also there is no use
of having late system sleep specifically for ADX device. Fix
the order by using normal system sleep.

The kcontrol put callback is expected to return 1 when there is change
in HW or when the update is acknowledged by driver. This would ensure
that change notifications are sent to subscribed applications. Filter
out duplicate updates in ADX driver.

The only usage of these is to assign their address to the ops field in
the snd_soc_dai_driver struct, which is a pointer to const. Make them
const to allow the compiler to put them in read-only memory.

The Audio Demultiplexer (ADX) block takes an input stream with up to
16 channels and demultiplexes it into four output streams of up to 16
channels each. A byte RAM helps to form output frames by any combination
of bytes from the input frame. Its design is identical to that of byte
RAM in the AMX except that the data flow direction is reversed.
This patch registers ADX driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes ADX interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver. It can be enabled in the DT via "nvidia,tegra210-adx"
compatible binding.
