  target/hppa: Avoid squishing DISAS_IAQ_N_STALE_EXIT

Within a delay slot, we were squishing both DISAS_IAQ_N_STALE and
DISAS_IAQ_N_STALE_EXIT to DISAS_IAQ_N_UPDATED.  This lost the
required exit to the main loop, and could result in interrupts
never being delivered.

  Update seabios-hppa to latest upstream

This patch fixes two issues in the hppa/parisc emulation:

1. The CPU HPA was wrong in the sense that we had negative module
offsets in the firmware-internal module table (which we ignored up to
now). Get it correct by changing the CPU HPA to 0xfffb0000 which is
greater than the DINO_HPA of 0xfff80000.
This change requires the seabios-firmware update.

2. Sven noticed that the FPU register cr10 is only able to reference up
to 8 FPUs, so let's reduce the maximum amount of SMP CPUs too.
