Helge Deller 87e126ea14 hw/hppa: Allow up to 16 emulated CPUs
This brings the hppa_hardware.h file in sync with the copy in the
SeaBIOS-hppa sources.

In order to support up to 16 CPUs, it's required to move the HPA for
MEMORY_HPA out of the address space of the new 16th CPU.
The new address of 0xfffff000 worked well for Linux and HP-UX, while
other addresses close to the former 0xfffbf000 area are used by the
architecture for local and global broadcasts.

The PIM_STORAGE_SIZE constant is used in SeaBIOS sources and
is relevant for the TOC/NMI feature.
