4.9-stable review patch. If anyone has any objections, please let me know.

commit f59cf9a0551dd954ad8b752461cf19d9789f4b1d upstream.
On rare occasions, we are still noticing that the internal speaker spitting out spurious noises even after adding the problematic codec to the list.
Adding a 10ms artificial delay before rebooting fixes the issue entirely.
Patch for Realtek codecs also adds the same amount of delay after entering D3.
