[U-Boot] [PATCH 1/2] serial: stm32x7: align compatible with kernel one

[patrice.chotard at st.com]

From: Patrice Chotard <patrice.chotard at st.com>

stm32x7.c driver is dedicated for STM32F7.
In kernel, "st,stm32-usart" and "st,stm32-uart" compatible
strings are dedicated for STM32F4.

To keep U-boot and kernel aligned, replace the serial compatible
string from "st,stm32-usart", "st,stm32-uart" to
"st,stm32f7-usart", "st,stm32f7-uart" specific for STM32F7.
