[PATCH 5.10 027/157] ASoC: SOF: intel: fix wrong poll bits in dsp power down
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit fd8299181995093948ec6ca75432e797b4a39143 upstream.
The ADSPCS_SPA is Set Power Active bit. To check if DSP is powered
down, we need to check ADSPCS_CPA, the Current Power Active bit.
