Some fixes and updates for SRAT/CEDT parsing code. Patches can be
applied individually and are independent.

First patch fixes a page fault during boot (fix as suggested by Dan).

Patches 2 to 4 remove architectural code no longer needed.

Patches 5 to 7 add diagnostic printouts for CEDT.

Changelog:

v6:
 * rebased onto cxl/fixes
 * fixed 0day build errors in patch #1:
   https://github.com/intel-lab-lkp/linux/commits/Robert-Richter/x86-numa-Fix-SRAT-lookup-of-CFMWS-ranges-with-numa_fill_memblks/20240429-205337

v5:
 * dropped: "x86/numa: Fix SRAT lookup of CFMWS ranges with
   numa_fill_memblks()"
 * added: "ACPI/NUMA: Return memblk modification state from
   numa_fill_memblks()"
 * conditionally print CEDT extended memblks

v4:
 * updated SOB chains and desription
 * added patch "x86/numa: Remove numa_fill_memblks() from sparsemem.h
   using __weak"
 * Reordered patches to move CEDT table printout as an option at the
   end
 * split print table patch and added: "ACPI/NUMA: Add log messages for
   memory ranges found in CEDT"

v3:
 * Rebased onto v6.9-rc1
 * Fixing x86 build error in sparsemem.h [Dan/Alison]
 * Added CEDT node info [Alison]
 * Use pr_debug() for table output [Dan]
 * Refactoring split in 3 patches [Dan]
 * Fixed performance regression introduced [kbot]
 * Fixed checkpatch issues [Dan]
