[PATCH] i2c: stm32: Use the correct style for SPDX License Identifier

[Nishad Kamdar]

This patch corrects the SPDX License Identifier style
in header file related to STM32 Driver for I2C hardware
bus support.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used)
