[PATCH 2/3] ASoC: codecs: lpass-wsa-macro: Prepare to accommodate new codec versions

From: Krzysztof Kozlowski
Date: Tue Jun 25 2024 - 12:59:42 EST

The driver for Qualcomm LPASS WSA macro codec was developed and tested
on codec v2.1, however v2.5 has significant changes in the registers.
The driver correctly works for v2.1 codec, but has issues when running
on SoC with v2.5 codec (so starting with SM8450, even though playback
works properly on that SoC).

Prepare the driver for handling differences in register layouts of newer
version. This does not have functional impact on older codec versions,
but just:
1. Renames few soc_enums and widgets as v2.1,
2. For registers being different in v2.5, moves the defaults and regmap
configuration to new structures,
3. Adds new 'struct wsa_reg_layout' with offsets and masks for few
registers, so most of the code can stay unchaged on v2.5,
4. Chooses proper widgets, regmap config and register layout based on
version of the codec.
