Antonio Borneo 382148e4dd openocd: fix SPDX tag format for files .c
With the old checkpatch we cannot use the correct format for the
SPDX tags in the file .c, in fact the C99 comments are not allowed
and we had to use the block comment.

With the new checkpatch, let's switch to the correct SPDX format.

Change created automatically through the command:
	sed -i \
	's,^/\* *\(SPDX-License-Identifier: .*[^ ]\) *\*/$,// \1,' \
	$(find src/ contrib/ -name \*.c)
