s390x/ipl: support diagnose 308 subcodes 5 and 6
To support dynamically updating the IPL device from inside the KVM guest on the s390 platform, DIAG 308 instruction is intercepted in QEMU to handle the request. Subcode 5 allows to specify a new boot device, which is saved for later in the s390_ipl device. This also allows to switch from an external kernel to a boot device. Subcode 6 retrieves boot device configuration that has been previously set.
