ASoC: qcom: fix SDM845 & QDSP6 dependencies more

Fix a build error and Kconfig warning in sound/soc/qcom/.

ld: sound/soc/qcom/qdsp6/q6afe-clocks.o: in function `q6afe_clock_dev_probe':
q6afe-clocks.c:(.text+0x182): undefined reference to `devm_clk_hw_register'
ld: q6afe-clocks.c:(.text+0x19d): undefined reference to `of_clk_add_hw_provider'

After adding "depends on COMMON_CLK" for SND_SOC_QDSP6, the Kconfig
warning appears because "select" does not honor any "depends on"
clauses, so fix the dependency for SND_SOC_SDM845 also.

WARNING: unmet direct dependencies detected for SND_SOC_QDSP6
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_QCOM [=y] && QCOM_APR [=y] && COMMON_CLK [=n]
  Selected by [y]:
