[PATCH v4 8/8] ASoC: qcom: lpass: Add support for LPASS codec v4.0

[Mohammad Rafi Shaik]

From: Prasad Kumpatla <prasad.kumpatla@xxxxxxxxxxxxxxxx>

Hawi and Maili use the LPASS codec v4.0, which the macro drivers do not
yet recognise.

Add LPASS_CODEC_VERSION_4_0 and its "v4.0" version string, and detect it
in the VA macro when the hardware reports major version 4, minor 0.

The RX macro register layout of LPASS codec v4.0 matches the v2.5+
layout, so reuse the existing v2.5 register access helpers, controls,
widgets and register defaults for it. Unlike v4.1, v4.0 does not need
the FS counter bypass or the adaptive filter blocks, so those stay keyed
off v4.1 only.

Add the "qcom,hawi-lpass-rx-macro" and "qcom,hawi-lpass-va-macro"
compatibles, both pointing at the sm8550 match data, so the version is
read back from the hardware at probe.
