Subject: [PATCH][V2] i2c: i2c-stm32f7: make structure stm32f7_setup static const

From: Colin Ian King <colin.king@...onical.com>

The structure stm32f7_setup is local to the source and does not need
to be in global scope, make it static const.

Cleans up sparse warning:
symbol 'stm32f7_setup' was not declared. Should it be static?
