ASoC: qcom: audioreach: add support for static calibration

This change adds support for static calibration data via ASoC topology
file. This static calibration data could include binary blob of data
that is required by specific module and is not part of topology tokens.

Reason for adding this support is to allow loading module specific data
that can not be part of the tplg tokens, example, Echo and Noise cancelling
module needs a blob of calibration data to function correctly.

This support is also one of the building block for adding speaker
protection support.

Tested this with Single Mic ECNS(Echo and Noise Cancellation).

tplg can now contain this calibration data like:

SectionWidget."stream2.SMECNS_V224" {
	...
	data [
		...
		"stream2.SMECNS_V224_cfg_data"
	]
}

SectionData."stream2.SMECNS_V224_cfg_data" {
	words "0x00000330, 0x01001006,0x00000000,0x00000000,
		0x00004145,0x08001026,0x00000004,0x00000000,
		..."
	}
}
