Subject: [PATCH 6/8] ASoC: codecs: lpass: fix incorrect mclk rate

For some reason we ended up with incorrect mclk rate which should be
1920000 instead of 96000, So far we were getting lucky as the same clk
is set to 192000 by wsa and va macro. This issue is discovered when there
is no wsa macro active and only rx or tx path is tested.
Fix this by setting correct rate.

Fixes: c39667ddcfc5 ("ASoC: codecs: lpass-tx-macro: add support for lpass tx macro")
Fixes: af3d54b99764 ("ASoC: codecs: lpass-rx-macro: add support for lpass rx macro")
