Since we have a common P2SB accessor in tree we may use it instead of
open coded variants.

Replace custom code by p2sb_bar() call.

Switch the GHES EDAC memory error reporting functions to use the common
CPER ones and get rid of code duplication.

  [ bp:
      - rewrite commit message, remove useless text
      - rip out useless reformatting
      - align function params on the opening brace
      - rename function to a more descriptive name
      - drop useless function exports
      - handle buffer lengths properly when printing other detail
      - remove useless casting

My previous patch had a typo/thinko which prevents this driver
from being enabled: change X64_64 to X86_64.

igen6_edac needs mce_register()/unregister() functions,
so it should depend on X86_MCE (or X86_MCE_INTEL).

That change prevents these build errors:

ld: drivers/edac/igen6_edac.o: in function `igen6_remove':
igen6_edac.c:(.text+0x494): undefined reference to `mce_unregister_decode_chain'
ld: drivers/edac/igen6_edac.o: in function `igen6_probe':
igen6_edac.c:(.text+0xf5b): undefined reference to `mce_register_decode_chain'

Simplify 32-bit and 64-bit Intel SoCFPGA Kconfig options by having only
one for both of them.  This the common practice for other platforms.
Additionally, the ARCH_SOCFPGA is too generic as SoCFPGA designs come
from multiple vendors.

Families up to and including 0x16 allow access to the injection
hardware. Starting with family 0x17, access to those registers is
blocked by security policy.

Limit that only on the families which support it.

Merge them into the main driver and put them inside an EDAC_DEBUG
ifdeffery to simplify the driver and have all debugging/injection stuff
behind a debug build-time switch.

No functional changes.
