Cleanup patch to remove the unnecessary copyright information in
the file, as it already has SPDX License Identifier.

No, you can not just drop copyright lines for no reason at all.  Did
your lawyers approve this patch?

Actually, I had planned to keep Microchip Copyright header for these
files later, as currently these files has the previous
company copyright information. 
I am not sure what will be right practice to either keep all
previous companies copyright or only the latest copyright information.

Its better to drop this for now and after consulting internally I will
submit the new patch.

SPDX identifes the _license_ of the file, not the copyrights, so it is
ok to drop these lines:

quoted

modify
- * it under the terms of the GNU General Public License version 2
as

As that is what it is replacing.  But not the copyrights.

Go show your lawyer this patch:

And see what they do :)

(yes, explicit copyright notices are really not needed and do not do
"much", but it is still the norm that they are present and our
industry does still rely on them...)

thanks,
