FROMLIST: ASoC: codecs: lpass-wsa-macro: Guard optional NPL clock rate programming

The NPL clock is only present on some platforms.  When it is absent,
wsa->npl remains NULL, but the driver unconditionally programs its rate.

Guard clk_set_rate() for the NPL clock so platforms without NPL do not
attempt to access it.

No functional change on platforms that provide the NPL clock.
