cnss: sdio: Define OOB interrupt interfaces.

Define the OOB interrupt interfaces in case that internal
interrupt is unsupported in some platforms.
In some specific platform, only polling mode is supported, with
these OOB interrupt interfaces implementation, it will support
interrupt mode.
To be generic, this OOB feature is default unsupported.
