target/hppa: Fix boot and reboot for SMP machines

Browse Source 
Fix some SMP-related boot and reboot issues with HP-UX and Linux by
 correctly initializing the CPU PSW bits, disabling data and instruction
 translations and unhalting the CPU in the qemu hppa_machine_reset()
 function.
 
 To work correctly some fixes are needed in the SeaBIOS-hppa firmware too,
 which is why this series updates it to version 8 which includes those
 fixes and enhancements:
 
 Fixes
 - boot of HP-UX with SMP, and
 - reboot of Linux and HP-UX with SMP
 
 Enhancements:
 - show qemu version in boot menu
 - adds exit menu entry in boot menu to quit emulation
 - allow to trace PCD_CHASSIS codes more specifically
