  target/hppa: Update SeaBIOS-hppa to version 18 (2025-01-30 14:16:58 +0100)

----------------------------------------------------------------
hppa 64-bit mfdiag improvements

The 64-bit hppa qemu emulation still fails to boot 64-bit HP-UX.
This patch series improves the emulation a lot, since it enables us to boot
64-bit HP-UX installer silently up until an endless loop where the machine
reports that it's up an running (it crashed before). This still needs further
analysis, but it's a big step forward.

Main changes to archieve this includes:
- Implementing diagnose registers (especially %dr2 for space-register hashing)
- a new SeaBIOS-hppa version 18, which includes those fixes and enhancements:
  - Fix IRT table entries to use slot number
  - Increase PCI alignment for memory bars to 64k
  - Fix PDC_CACHE/PDC_CACHE_RET_SPID return value
  - Allow up to 256 GB RAM on 64-bit machines
