[PATCH 1/2] powerpc/fadump: remove old sysfs symlink

[Sourabh Jain]

Commit d418b19f34ed ("powerpc/fadump: Reorganize /sys/kernel/fadump_*
sysfs files") and commit 3f5f1f22ef10 ("Documentation/ABI: Mark
/sys/kernel/fadump_* sysfs files deprecated") moved the
/sys/kernel/fadump_* sysfs files to /sys/kernel/fadump/ and deprecated
the old files in 2019.

To maintain backward compatibility, symlinks were added at the old
locations so existing tools could still work. References [1][2] now use
the new sysfs interface, so we can safely remove the old symlinks.
