Nishad Kamdar 5a158981aa siox: Use the correct style for SPDX License Identifier
This patch corrects the SPDX License Identifier style in
header file related to Eckelmann SIOX driver.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

Changes made by using a script provided by Joe Perches here:
