ASoC: codecs: lpass: add support for v2.5 rx macro

Merge series from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

This patchset adds support to reading codec version and also adds
support for v2.5 codec version in rx macro.

LPASS 2.5 and up versions have changes in some of the rx blocks which
are required to get headset functional correctly.

Tested this on SM8450, X13s and x1e80100 crd.

This changes also fixes issue with sm8450, sm8550, sm8660 and x1e80100.
