On reporter's machine with Intel controller (8086:1e20) + VIA VT1802 codec, the first playback slot can't work with speaker outputs. But the original commit was actually a fix for AMD controllers where no proper GCAP value is returned, we shouldn't revert the whole commit. Instead, in this patch, a new flag is introduced to determine the stream assignment order, and follow the old behavior for Intel controllers.

However, since the probe was done asynchronously, the driver object still remains, thus the relevant PM ops are still called at suspend/resume. This results in the bad access to the incomplete audio card object, eventually leads to Oops or stall at PM. This patch adds the missing checks of chip->init_failed flag at each PM callback in order to fix the problem above.
