Many watchdog drivers's source files has already SPDX license
identifier, while some remaining doesn't.

Convert notices on remaining files to SPDX identifier. While at it,
also move SPDX identifier for drivers/watchdog/rtd119x_wdt.c to the
top of file (as in other files).

Shouldn't this be
// SPDX-License-Identifier: GPL-1.0 OR GPL-2.0
(or in current SPDX notation GPL-1.0-only OR GPL-2.0-only) ?

This would include GPL 3, but the text below explicitly excludes that.
No idea how to handle that.

Oops, still incorrect tag. Will fix in v3 (should be out on next Monday).

Nope, as it will fail spdxcheck.py. Also, SPDX specification [1]
doesn't have negation operator (NOT), thus the licensing requirement
on the above notice can't be expressed reliably in SPDX here.

The GPL identifiers in recent versions of SPDX include an `-only` and
an `-or-later` variant. So I don't see why you can't represent it as
`GPL-1.0-only OR GPL-2.0-only`. From what I understand the kernel
requires/prefers use of the earlier approach to GPL identifiers (which
was better in my opinion) under which `GPL-1.0 OR GPL-2.0` would at
least be semantically similar. I don't see why you need a negation
operator in this case. You have other patches where you used the
`-only` identifiers.

But Linux does not use the newer versions of SPDX given that we started
the conversion before the "-only" variant came out.  Let's stick with
the original one please before worrying about converting to a newer
version of SPDX and mixing things up.

Either case I'd prefer to have no conversion if there is no means
to express the original license (ie GPL-1.0 or GPL-2.0 and nothing else)
in acceptable SPDX form.
