Docs/admin-guide/mm/damon/usage: remove redundant information 

DAMON usage document mentions DAMON user space tool and programming
interface twice.  This commit integrates those and remove unnecessary
part.

DAMON provides below three interfaces for different users.
- *DAMON user space tool.*
This is for privileged people such as system administrators who want a
just-working human-friendly interface. Using this, users can use the DAMON’s
major features in a human-friendly way. It may not be highly tuned for
special cases, though. It supports both virtual and physical address spaces
monitoring.
`This <https://github.com/awslabs/damo>`_ is for privileged people such as

Using this, users can use the DAMON’s major features in a human-friendly way.
It may not be highly tuned for special cases, though. It supports both
virtual and physical address spaces monitoring. For more detail, please
refer to its `usage document
<https://github.com/awslabs/damo/blob/next/USAGE.md>`_.
- *debugfs interface.*
This is for privileged user space programmers who want more optimized use of
DAMON. Using this, users can use DAMON’s major features by reading
from and writing to special debugfs files. Therefore, you can write and use
your personalized DAMON debugfs wrapper programs that reads/writes the
debugfs files instead of you. The DAMON user space tool is also a reference
implementation of such programs. It supports both virtual and physical
address spaces monitoring.

supports both virtual and physical address spaces monitoring.
- *Kernel Space Programming Interface.*
This is for kernel space programmers. Using this, users can utilize every
feature of DAMON most flexibly and efficiently by writing kernel space
DAMON application programs for you. You can even extend DAMON for various
address spaces.
:doc:`This </vm/damon/api>` is for kernel space programmers. Using this,
users can utilize every feature of DAMON most flexibly and efficiently by
writing kernel space DAMON application programs for you. You can even extend
DAMON for various address spaces. For detail, please refer to the interface
:doc:`document </vm/damon/api>`.
Nevertheless, you could write your own user space tool using the debugfs
interface. A reference implementation is available at
https://github.com/awslabs/damo. If you are a kernel programmer, you could
refer to :doc:`/vm/damon/api` for the kernel space programming interface. For
the reason, this document describes only the debugfs interface
