Peter Maydell d0f4aa7d50 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
