Update SVD for STM32F7x9

[A-Yerkesh]

STM32F7x9.svd didn't generate bindings, raising this error:

Fatal error when parsing the SVD file:
STM32F7x9.svd:22934:7: Name differ for closing tag (expecting register, opened line 22567)

I replaced it with the newer version, taken from here

FWIW the new version changes a few other things than just fixing the incorrect XML markers. Have you tested this against the Ada_Drivers_Library? If not I can have a look.

I ran tests on Ada Drivers Library's master. Then i replaced STM32F7x9.svd in svd2ada/CMSIS-SVD/ST/, navigated to Ada_Drivers_Library/arch and ran make -f svd.mk. After that i ran tests again. In both cases, there are 8 identical failures:
