f821a3c174 zdump: Drop support of 32-bit dump architecture 
- Initialize dump and dump-tool architecture to DFI_ARCH_64 at the start
  of dfi_init() and dt_init() respectively.
- Bail out if any dump architecture other than ARCH_64 has been detected
  in s390_ext or s390mv_ext DASD dump header.
- Remove redundant dfi_arch_set() and dt_arch_set() functions.
- Get rid of l.arch local variables in dfi* and dt* source files and
  drop dfi_arch() function.
- Drop the usage of DFI_ARCH_32 and compeletely remove DFI_ARCH_UNKNOWN.
- Drop special register and lowcore processing functions used
  for DFI_ARCH_32.
- Drop df_s390_from_dfi_arch() and df_s390_to_dfi_arch() funcitons.
- Update the man file for zgetdump.

Make 'zgetdump -d' to identify ldipl-dump tool (ngdump) installed on DASD
volume just like it does for NVMe ngdump.

Output sample:
-------------
Dump device info:
  Dump tool.........: Next Generation (NGDump) dump tool
  Version...........: 1
  Architecture......: s390x (64 bit)

Partition info:
  Partition number..: 2

0466760ec1 zdump: Implement DT interface for NGDump 
The NGDump DT interface enables zgetdump to display various meta
information contained within a dump partition prepared for NGDump
stand-alone dump.

Usage example:
--------------

No dump yet made
----------------

$ zgetdump -d /dev/nvme0n1
Dump device info:
  Dump tool.........: Next Generation (NGDump) dump tool
  Version...........: 1
  Architecture......: s390x (64 bit)

Partition info:
  Partition number..: 1

Dump present
------------

$ zgetdump -d /dev/nvme0n1
Dump device info:
  Dump tool.........: Next Generation (NGDump) dump tool
  Version...........: 1
  Architecture......: s390x (64 bit)

Partition info:
  Partition number..: 1
Meta info:
  File..............: dump.elf

Alternative disk path
---------------------

$ zgetdump -d /dev/disk/by-id/nvme-eui.01000000010000005cd2e4c5bc845051
Dump device info:
  Dump tool.........: Next Generation (NGDump) dump tool
