[Fix] After resuming, the driver needs to restore 2 more registers, then the dmic could record the sound. [Test Case] Boot the kernel with this patch, open the sound-setting and run suspend and resume, then use arecord to record the sound, verify the sound is successfully recorded by aplaying it. [Regression Risk] Low, this patch is verified on the amd renoir machine, and this patch got ack from AMD engineer.
