Currently, FADump sysfs files are present inside /sys/kernel directory.
But as the number of FADump sysfs file increases it is not a good idea to
push all of them in /sys/kernel directory. It is better to have separate
directory to keep all the FADump sysfs files.

The patch series reorganizes the FADump sysfs files and avail all the
existing FADump sysfs files present inside /sys/kernel into a new
directory /sys/kernel/fadump. Currently, all the FADump sysfs files
are replicated into a new directory to maintain the backward compatibility
and will eventually get removed in future. In addition to this a new FADump
sys interface is added to get the amount of memory reserved by FADump for
saving the crash dump.

Changelog:

v1->v2:
 - Move fadump_release_opalcore sysfs to FADump Kobject instead of
   replicating.
 - Changed the patch order 1,2,3,4 -> 2,1,3,4 (First add the ABI doc for
   exisiting sysfs file then replicate them under FADump kobject).

v2->v3:
 - Remove the fadump_ prefix from replicated FADump sysfs file names.
