[U-Boot] [PATCH 8/8] patman: Add Series-process-log tag to sort/uniq change logs

[Simon Glass <sjg@chromium.org>]

For some series with lots of changes it is annoying that duplicate change
log items are not caught. It is also helpful sometimes to sort the change
logs.

Add a Series-process-log tag to enable this, which can be placed in a
commit to control this.

The change to the Cc: line is to fix a checkpatch warning.
