paul luse eb53c23236 add (c) and SPDX header to bash files as needed
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc)

For intel copyrights added, --follow and -C95% were used.
