ASoC: tegra: Fix MBDRC bypass mode check

MBDRC supports different modes of operation. There is no configuration
required for bypass mode. The hw_params() call does not filter bypass
mode correctly and it leads to following Smatch static checker warning:

sound/soc/tegra/tegra210_mbdrc.c:778 tegra210_mbdrc_hw_params()
warn: bitwise AND condition is false here

Fix this condition by using proper mode mask and just return for bypass
mode.

ASoC: tegra: Add Tegra210 based OPE driver

The Output Processing Engine (OPE) is one of the AHUB client. It has
PEQ (Parametric Equalizer) and MBDRC (Multi Band Dynamic Range Compressor)
sub blocks for data processing. The PEQ block gets samples from the MBDRC
block.

This patch registers OPE driver with ASoC framework. The component driver
exposes DAPM widgets, routes and kcontrols for the device. The DAI driver
exposes OPE interfaces, which can be used to connect different components
in the ASoC layer. Makefile and Kconfig support is added to allow build
the driver.
