  target/hppa: Update SeaBIOS-hppa to version 15 (2024-01-13 06:49:18 +0100)

----------------------------------------------------------------
target/hppa qemu v8.2 regression fixes

There were some regressions introduced with Qemu v8.2 on the hppa/hppa64
target, e.g.:

- 32-bit HP-UX crashes on B160L (32-bit) machine
- NetBSD boot failure due to power button in page zero
- NetBSD FPU detection failure
- OpenBSD 7.4 boot failure

This patch series fixes those known regressions and additionally:

- allows usage of the max. 3840MB of memory (instead of 3GB),
- adds support for the qemu --nodefaults option (to debug other devices)

This patch set will not fix those known (non-regression) bugs:
- HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine
- Linux kernel will still fail to boot on C3700 as long as kernel modules are used.

Changes v2->v3:
- Added comment about Figures H-10 and H-11 in the parisc2.0 spec
  in patch which calculate PDC address translation if PSW.W=0
- Introduce and use hppa_set_ior_and_isr()
- Use drive_get_max_bus(IF_SCSI), nd_table[] and serial_hd() to check
  if default devices should be created
- Added Tested-by and Reviewed-by tags

Changes v1->v2:
- fix OpenBSD boot with SeaBIOS v15 instead of v14
- commit message enhancements suggested by BALATON Zoltan
- use uint64_t for ram_max in patch #1
