arm64: dts: qcom: sm8650: drop unneeded assigned-clocks from WSA macro

Review of v1 patch resulting in commit 58872a54e4a8 ("arm64: dts: qcom:
sm8650: add ADSP audio codec macros") pointed to remove unneeded
assigned-clock-rates from macro codecs.  One assignment was left in WSA
macro codec, so drop it now as it is redundant: these clocks have fixed
19.2 MHz frequency.
