Subject: [PATCH] ASoC: codecs: lpass-va-macro: set the default codec version for sm8250

From: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>

sm8250 and sc7280 have lpass codec version 1.0, as these are very old
platforms, they do not have a reliable way to get the codec version
from core_id registers.

Add the version info into of_data, so that it does not need to use
core_id registers to get version number.

Fixes: 378918d59181 ("ASoC: codecs: lpass-macro: add helpers to get codec version")
Fixes: dbacef05898d ("ASoC: codec: lpass-rx-macro: prepare driver to accomdate new codec versions")
Fixes: 727de4fbc546 ("ASoC: codecs: lpass-wsa-macro: Correct support for newer v2.5 version")
