a class to cpu-qom.h. This helps making files independent of NEED_CPU_H

Just leave some members in even if they are unused on e.g.
32-bit PPC or user-mode emulation. This avoids complications
when using PowerPCCPUClass in code that is compiled just
once (because it applies to both 32-bit and 64-bit PPC
for example) but still needs to peek at PPC-specific members.

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.
