b78400e416 ASoC: tegra: Use normal system sleep for Mixer 
The driver currently subscribes for a late system sleep call.
The initcall_debug log shows that suspend call for Mixer 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 Mixer device. Fix
the order by using normal system sleep.

8cf72c4e75 ASoC: tegra: Fix kcontrol put callback in Mixer 
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 Mixer driver.

313fab4820 ASoC: tegra: Constify static snd_soc_dai_ops structs 
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.

05bb3d5ec6 ASoC: tegra: Add Tegra210 based Mixer driver 
The Mixer supports mixing of up to ten 7.1 audio input streams and
generate five outputs (each of which can be any combination of the
ten input streams)

This patch registers Mixer driver with ASoC framework. The component
driver exposes DAPM widgets, routes and kcontrols for the device.
The DAI driver exposes Mixer 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-amixer" compatible binding.
