ASoC: sigmadsp: Add support for fw v2

Browse Source 
This patch adds support for the v2 version of the SigmaDSP firmware file
format. The new format has support for having different program and
parameter settings for different samplerates. In addition it stores metadata
describing the firmware. This metadata includes the set of supported
samplerates which will be used to restrict the samplerates that can be
selected by userspace. Also included is information about the modifiable
parameters. Those will be exposed as ALSA controls so they can be changed at
runtime.

The new format is based on a binary type-length-value structure that makes
it both forward and backwards compatible.
