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.

@Neil Armstrong  can you pl test it on sm8650

@Krzysztof Kozlowski can you pl test it on sm8550

Thanks,
Srini

Changes since v1:
 - renamed all 2_6 variables with 2.5
 - expanded checks for versions from 2.5 till 2.8

So it's possible for two platforms have the same LPASS IP version, but
different codec versions?

Is it really just a global variable, no locking, no device?

Tested-by: Neil Armstrong <neil.armstrong@linaro.org> # on SM8650-HDK

Successfully fixes dual channel output on headset, previously I would only hear
sound on a single channel.

Thanks,
Neil
