On certain places it is required to flush output print buffers to ensure that text strings were sent to console or serial devices. For example when printing message that U-Boot is going to boot kernel or when U-Boot is going to change baudrate of terminal device. Therefore introduce a new flush() and fflush() functions into console code. These functions will call .flush callback of associated stdio_dev device. As this function may increase U-Boot side, allow to compile U-Boot without this function. For this purpose there is a new config CONSOLE_FLUSH_SUPPORT which is enabled by default and can be disabled. It is a good idea to have this option enabled for all boards which have enough space for it. When option is disabled when U-Boot defines just empty static inline function fflush() to avoid ifdefs in other code.
