Subject: [PATCH 1/2] ASoC: codecs: lpass-tx-macro: set npl clock rate correctly

NPL clock rate is twice the MCLK rate, so set this correctly to
avoid soundwire timeouts.

Fixes: c39667ddcfc5 ("ASoC: codecs: lpass-tx-macro: add support for lpass tx macro")
Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@...aro.org>
