dt-bindings: rcc: stm32: Fix STM32MP13 include file

  Minor cosmetic change, aligned with files in U-Boot:
- change obsolete SPDX id : GPL-2.0+
- use correct address gabriel.fernandez@foss.st.com
- remove extra space

Make the subject reflect the purpose: 'Sync with u-boot copy'

Really, the Linux copy came first, so you should use its license. Your 
company's lawyers are good with GPLv3 and then v4?

We have a long debate on the licenses, and particular for device tree,

and as conclusion we are using for STM32MP SoCs:

- For code (in Linux kernel driver) => GPL-2.0-only

- For device tree and binding .h files; the dual licenses => 
GPL-2.0-or-later OR BSD-3-Clause


It is because the modifications in device tree files and binding file s 
can be applied on

other SW with using any licenses:

    - GPL2 (Linux /u-Boot)

    - BSD (TF-A/OP-TEE)

    - GPL3/GPL4 license (any other SW component)


Just indicate GPL-2.0-or-later in the device tree or binding files won't 
contaminate

all the projects with GPL3/GPL4 license if it only use this DT, or 
binding files.


NB: it is already the case for other files used by STM32MP SoC, for 
example :

./include/dt-bindings/pinctrl/stm32-pinfunc.h:
     /* SPDX-License-Identifier: (GPL-2.0+ OR BSD-3-Clause) */


and we have no reason to use a different license for the 2 files for 
STM32MP13 RCC binding:

   include/dt-bindings/reset/stm32mp13-resets.h
   include/dt-bindings/clock/stm32mp13-clks.h

This patch corrects a mistake in the initial commit for RCC binding 
up-streamed

by Gabriel in parallel in U-Boot and Linux repositories; this 
inconsistency in the license

was corrected only when the same patch was pushed in U-Boot.


PS: using the GPL2-only is not a issue for U-Boot but perhaps for other 
user of device tree in other components,
       So if it is a blocking issue for Linux I can change it to 
"GPL-2.0-only" in Linux and U-Boot

Hi,


after test and to avoid the check-patch issue on next branch introduced 
by commit a04bb4c24a48

("checkpatch: introduce proper bindings license check"),

I will use the same license for the 2 files "GPL-2.0-only" as recommended in

https://lore.kernel.org/all/CAL_Jsq+-YJsBO+LuPJ=ZQ=eb-monrwzuCppvReH+af7hYZzNaQ@mail.gmail.com

=> "Also, GPL-2.0-or-later is neither desired nor encouraged."

And I will align the U-Boot files later....
