[PATCH] serial: stm32: make info structs static to avoid sparse warnings

[Ben Dooks <ben-linux@fluff.org>]

The info structs are local only to the stm32-usart.c driver and are
triggering sparse warnings about being undecalred. Move these into
the main driver code and make them static to avoid the following
warnings:

drivers/tty/serial/stm32-usart.h:42:25: warning: symbol 'stm32f4_info' was not declared. Should it be static?
drivers/tty/serial/stm32-usart.h:63:25: warning: symbol 'stm32f7_info' was not declared. Should it be static?
drivers/tty/serial/stm32-usart.h:85:25: warning: symbol 'stm32h7_info' was not declared. Should it be static?
