ENGR00118226 MX35 PM: System crashes when try to wake up from standby

The ak4647_codec is not initialized as there is no ak4647 codec existing
on MX35 board. In the 31 kernel, the card and codec drivers are
registered separately, and there is no check whether the codec is probed
successfully or not. On MX35 board, the card is sucessfully registered,
but there is no ak4647 codec. In this case, the system will crash if the
system try to invoke the codec's resume function.
To resolve the problem, add a check in registering the card. If the
codec does not exist, give up registering the card either.
