UBUNTU: [Config] s390: Build ap driver into the kernel

BugLink: https://bugs.launchpad.net/bugs/2116061

The adjunct processor (AP) bus driver is currently configured as a loadable module.
This leads to a bug on systems that rely on early access to hardware
cryptographic resources. In particular, encrypted root filesystems using secure keys
may fail to boot if the AP module is not available at boot.

Fix the issue by building the AP driver into the kernel.
