ALSA: hda - Add some workarounds for Creative IBG

Creative HD-audio controller chips require some workarounds:
 - Additional delay before RIRB response
 - Set the initial RIRB counter to 0xc0

The latter seems to be done in general in Windows driver, so we may
use this value later for all types if it's confirmed to work better.
