pc-bios/s390-ccw: Get device address via diag 308/6
To IPL from a device, pc-bios receives from qemu a device address via general register 7. The better way to do it is to use diag308/6 instruction which returns so called "IplParameterBlock". IplParameterBlock contains the device address for IPL and additional parameters that can be used by pc-bios. This patch allows pc-bios to get device address via diag308/6 and doesn't use gr7 passed boot information anymore.
