[PATCH v3 3/4] ASoC: tegra: Specify components string for each card

[Dmitry Osipenko]

Specify components string for each card of each supported device. It's
a free form string that describes audio hardware configuration. This
information is useful for ALSA UCM rules. It allows to generalize UCM
rules, potentially removing a need to add new UCM rule for each device.

This patch also adds asoc->components hook that allows to specify
components description per device.
