Add console_core_flush() in upstream platforms
It is needed to add placeholders for this function because, as this is
not a `plat_xxx()` function, there aren't weak definitions of it in any
file.
If `console_flush()` is used and there isn't an implementation of
`console_core_flush()` in any file, the compilation will fail.
