ALSA: hda - Restore GPIO1 properly at resume with AD1984A

Browse Source 
The commit 099db17e66 introduced a
regression at suspend/resume where the GPIO1 bit isn't properly
restored, thus the speaker output gets muted initially after resume.

The fix is simple, use the cached write for storing GPIO data.
