Since commit 7b3b74d32127 ("serial: serial_stm32: Enable overrun")
on STM32F7xx based boards, the first lines of serial output are
missing during boot (we no more see the U-Boot release version,
board model and DRAM size).
By enabling the uart FIFO on STM32F7, the complete U-boot log
can be sent correctly.

Applied to u-boot/master, thanks!
